Brackets being very very slow suddenly

[larrby]

I started using Brackets today and it was very very slow. It takes a couple of seconds when clicking at places and writing things for it to respond. I have 150 lines of code in my file, and the lag seems to get better when removing code; in a .js file with only a few lines of code there doesn't seem to be any lag at all. The lag persists in html, css and js files.

I've tried loading without extensions, following this to clear the cache, uninstalling, rebooting and reinstalling a number of times, installing an old version 1.8, installing the newest version, running as administrator, none seem to work. I'm using Windows 10 64 bit.

Nothing really changed between yesterday when there were no issues and today except I opened up LightTable once after a long time of not using it.

[rensvandewiel]

I have the same issue. Been working normally today. Then Windows 10 did a small update for me later in the afternoon. And now when I use Brackets there is a lot of lag while scrolling / typing. I hit around 60% CPU usage on an 3GHz i7. It might have to do with a .NET update. But I'm not sure.

[jbmonroe]

Ditto here. I thought maybe it was JSHint, but I just disabled that and there's no difference. The size of the file involved doesn't make it come back to 'live' status any more quickly, and it even happens when resuming focus after inspecting a different app window. It hangs on my 18-line brackets.json file.

Here's the health report data:

[jbmonroe]

Tried this: https://github.com/adobe/brackets/wiki/Troubleshooting#-brackets-is-running-slow

No change.

[Rain64]

Yeah, the scrolling speed is super slow, this is pretty annoying...

[jbmonroe]

If I focus on another window and come back, it delays the registration of my even closing the window. I'm trying to get onto the Slack channel to see if I can get some feedback.

[larrby]

I had no issues on my Windows 10 64bit tablet, then I installed all the latest Windows updates and now have slight lag or choppiness with Brackets. It's tolerable but not quite as fast as before.

[XavierCrespin]

I can confirm this too, the latest windows update kb4343909 crippled brackets on all my machines, i had to roll back to another text editor in order to continue my projects, it's unusable.
Disabling all extensions has no effect on the performance issue.
Every click, scroll, type has a 1-2 seconds lag.

[rensvandewiel]

Yeah, I can with most certainty say it's the latest Windows 10 update...

Well, in hindsight, it made me push myself to finally setup Sublime properly, and my own localhost setup. I can actually work a lot faster now. Though Sublime does not have the JavaScript IDE depth as Brackets, it definitely is a smooth coding experience after installing a few packages.

[jbmonroe]

My personal machine doesn't seem to have the issue. Perhaps it's a difference between Win 10 Pro and Win 10 home patching. In the meantime I'm just limping along with VS Code. 😜

[aga87]

Hi, I have the same issue - any editing to my html file is very slow, there is a few seconds lag when typing and deleting. I am new to coding and was just getting familiar and comfortable with Brackets, when I discovered this issue yesterday. I have very few extensions installed and working on my first projects, so my working files are very simple and short. The editor seemed to be working much quicker though last time I used it (max a few weeks ago). I see some users suggesting here that it has to do with Windows 10 update - I have Windows 10 Pro and still experiencing the issue. Any idea as to when we can expect to get it solved? Is there anything on my end I can do to fix it? Or should i be looking for a new code editor meanwhile? Thanks

[jbmonroe]

They'll get it fixed eventually--Brackets is a decent product and stuff like this happens from time to time on cutting-edge software. VSCode is the go-to for me right now. It doesn't have the close relationship to Chrome that Brackets has, but it has all the features you'd want and it works as a pretty decent development and debugging environment for Electron apps as well.

[XavierCrespin]

Or should i be looking for a new code editor meanwhile?

You probably should, although this is a major issue that renders the software unusable, it seems it has not caught any attention from the devs yet. If you're just looking for a simple text editor in the meanwhile with syntax coloring, may i suggest notepad++ ?

[jbmonroe]

Notepad++ is good, Bowpad is good (although not very well known), Sublime Text is good (but not free). Boxer (texteditor.com) is also good--but again, not free.

I still haven't figured out how to get into the Brackets slack channel to bring some attention to the speed issue.

[samthill]

Experiencing the same, and kind of relieved to see others are too, in the hope that this will get fixed soon. I've been pushing on with it, but will have to switch today as it's slowing development down too much.

[silentcolours]

I can 100% confirm it is the most recent Windows Update causing this problem for me. (August 14, 2018—KB4343909 (OS Build 17134.228)

I rolled back the update (uninstalled it) and brackets runs perfectly smooth again. (As well as a few other OS glitches and blue screens have now ceased.)

[navch]

@silentcolours I am on the same version of windows but I am not seeing any slowness. Can we debug this issue on some machine where this is easily reproable?

[jbmonroe]

Pro or Home? I have the issue on Pro but not on Home.
I also don't seem to have KB4343909 applied--looked for it with DISM and systeminfo. Nothing came up. There may be more than one trigger for the behavior.

[silentcolours]

@navch I am happy help. but i will need to be guided step by step through any processes you may need to debug. (im not very savy)

@jbmonroe Home Edition. You may have done this already - but "Settings/Windows Update/View Update History" Is where i found and uninstalled it.

I am going to reinstall it and see if the problem returns..

Update

Reinstalled the update (KB4343909) and restarted. And the lag is immediately back. Brackets is the only things running on the laptop and i have a .html .css .js .scss files open. None of them have more than 90lines of code in them.

Super smooth before the update. Super laggy after.

[jbmonroe]

@silentcolours On Windows Home I have KB4343909 installed and don't have the problem. At work I don't have KB4343909 installed and do have the problem. All I get from that is that KB4343909 can be a contributing factor, but maybe not the only one.

[larrby]

I uninstalled the KB4343909 security update and Brackets works perfectly.

[jbmonroe]

We should compare extensions and plugins.

Home machine (no symptoms)

• Brackets Pryme Theme - Dark
• Generic Dark
• JSHint (Raymond Camden)
• New Html5 Document (Yasin Kuyu)

I'll have to wait until I can get onto the work laptop to get its list, but it wouldn't differ widely because I don't use a lot of extensions with Brackets normally.

[KBROU]

I uninstalled Windows 10 Security update (KB4343909) and it seems to be working now.
Path: Settings/Windows Update/View Update History

[XavierCrespin]

I apologize for being straightforward, but removing a security update should not be considered as an acceptable workaround, any news on the advancement ?

[jbmonroe]

My work machine has the same two active extensions, and replaces the two themes with VSCode Dark only.

@XavierCrespin You won't see any movement until this changes:

Assignees
No one assigned
Labels
None yet
Projects
None yet
Milestone
No milestone

Right now I don't think this is at the forefront of their attention. I still haven't gotten an invite to the Slack channel despite two requests.

[XavierCrespin]

Thanks @jbmonroe , hadn't noticed.
The problem occurs regardless of extensions too.

[navch]

Thanks @silentcolours for helping on this. We can connect on BlueJeans. Please send a personal message on brackets slack workspace. Is that fine?

[jbmonroe]

Good to know @XavierCrespin -- that's one of the "usual suspects" eliminated. There was a long-ago issue with JSHint slowing down Brackets, so I thought it might be wise to take those out of the equation.

[CarlosBercero]

Maybe Brackets is secretly trying to exploit the vulnerability this security update addresses... just saying...

[jbmonroe]

I will not get distracted by explaining that Adobe wouldn't want to fend off a lawsuit that big.

[CarlosBercero]

Agree. Just joking around to see if this draw their attention and fix this problem.

BTW, removing that Windows update indeed fixed the problem, and also improved overall performance on my computer, and I'm using Home Edition.

[pokedoh]

I tried that and it does nothing to remedy the issue.

[Andrew-Snell]

Hi @lazanf

I am using Windows 10 machine, I am using the --enable-renderer-accessibility instead of --disable-renderer-accessibility, my installation of brackets is working fine. Just add it to your icon shortcut path.

Regards
Andrew

[nethip]

@Andrew-Snell Could you try this build https://www.dropbox.com/s/5y55yl4tos9zxdw/Brackets-Release.zip?dl=0 and let me know if it is working for you ( without the --enable-renderer-accessibility switch)?

[BartzikWebdesign]

Also Brackets is freezing for several seconds when I try to copy code in a new generated file.
For example copying https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js to a local file in my project freezes Brackets for minutes until I can do anything else.

When doing this, Brackets is using about 26% of my CPU. Normaly it should be 1 or 2 % maximum.

Disabling all plugins has no effect.

UPDATE:
The previous build (https://www.dropbox.com/s/5y55yl4tos9zxdw/Brackets-Release.zip?dl=0) workes fine on both problems for me.

[nethip]

@BartzikWebdesign Thanks for confirming!

Currently, we are testing the windows build, and we will be doing a dot release of Brackets to fix this performance issue in a few days.

[micahhlc]

Mac 10.13.4. it has been unresponsive for many weeks until today i really can't tolerate. when I looked up the www and found many people having same issues.

[Andrew-Snell]

Hi @larrby

Did you come right with brackets ?.

Regards
Andrew

[larrby]

@Andrew-Snell I haven't used Brackets in a while but the fix released before works ok.

[Andrew-Snell]

Hi @larrby

I been using brackets for the last two months without any issues, It's nice to chat to you again larrby.

Regards
Andrew

[ithinkmatt]

Starting this week Brackets is so slow it's unusable on Windows. Moving to VS Code. Not sure I'm going to keep trying Brackets since the performance issues keep reappearing.

[jbmonroe]

@ithinkmatt Did that coincide with a Windows patch? My Win10 Pro instance worked just fine yesterday.
My Win Home instance seems to be okay as well.
Release 1.13 build 1.13.0-17696 (release 49d29a8)
build timestamp: Thu Jun 14 2018 08:13:54 GMT+0100

The biz instance is the same:
Release 1.13 build 1.13.0-17696 (release 49d29a8)
build timestamp: Thu Jun 14 2018 08:13:54 GMT+0100

So far, so good....

[Andrew-Snell]

Hi @jbmonroe

My laptop is running a bit slow since I did a windows update a few days ago, but brackets is working fine for the last two months.

Andrew

[ayushrathi15]

Hi All,

We have addressed this issue and have refreshed the windows build.
The new build can be downloaded from below location :
https://github.com/adobe/brackets/releases/download/release-1.13/Brackets.Release.1.13.msi

Please let us know if you are still experiencing any performance issues with the new build.

Thanks and Regards
Ayush Rathi

[ithinkmatt]

@jbmonroe @ayushrathi15 I don't believe a Windows update coincides with the issues I was experiencing. I ended up uninstalling Brackets and am currently testing Atom with several packages. I'm really liking Atom due to the customization available through different packages to customize and extend the use. Unfortunately, I may stay with Atom, but will install the Brackets update soon to let you know if the updated build resolved the issue.

[jbmonroe]

I haven't had a problem with it on Windows 10 Home--I haven't had the opportunity to check it on Windows 10 Pro because I'm on vacation.

[hpeikari]

Brackets is really unstable. It keeps freezing all the time. I am finally switching to another Editor permanently. I'm done with this unstable tool.

[jbmonroe]

@hpeikari For the sake of helping the team track down the issue, what size file were you editing? What sort of file was it? What extensions did you have enabled? What operating system?

Not required, naturally, but I'm sure the team would appreciate the info. (Disclaimer: I'm not on the team.)

[hpeikari]

JS file , about 50 line of code , probably 2kb
Windows 10, Lenovo T470

My Brackets froze like 10 times since last week when I installed the latest version. It caused me losing a lot of unsaved works. I switched to Visual Studio Code.

[jbmonroe]

Windows 7? 10? Pro or Home?

[uniqorn2009]

I am having the same problem as the rest of you. I've used Brackets before but not on a regular basis. I'm using it now to follow a tutorial and it lags especially when adding spaces with the enter button or the tab key. I just downloaded and installed the new update
Release 1.13 build 1.13.1-17699 (windows-release-1.13.1 fc2ebbe)
build timestamp: Mon Dec 03 2018 09:26:27 GMT+0000
But there was no help. It still lags.
I have about 10 extensions intalled. Working on a PHP file with less than 20 lines

[artbrander]

Yeah, I tried the whole accessibility flag trick mentioned above, which worked, and then there was a Brackets update, which worked, and then all of a sudden it stopped working again and not even the accessibility flag fixed it. I loved Brackets but I ended up switching to VS Code. Hope they get it fixed though.

[new103]

Hi @lazanf

I am using Windows 10 machine, I am using the --enable-renderer-accessibility instead of --disable-renderer-accessibility, my installation of brackets is working fine. Just add it to your icon shortcut path.
