Emacs freezes for 10-12 seconds

[manfredlotz]

Running Fedora 22, Emacs 24.5.1 and spacemacs-0.104.2.

If I start Emacs, then do SPC f e h, then select org, and do a search for some string Emacs freezes for 10-12 seconds. CPU is at 100%.

If I start Emacs then load ~/.emacs.d/layers/org/README.org directly, and do the same search for a string then there is no freeze.

I observed that when doing SPC f e h emacs seems to load every layer available which looks weird.
Here the beginning of the messages.

Open the quickhelp.

Any idea what could cause it?
Thanks, Manfred

Emacs freeze too with | char in a lambda function in Ruby files.

I just observerd that the freeze takes place if I search for the string 'link'. I searched for other strings and no freeze happened. If I search for 'link' in other documents, e.g. in the Django documentation, no freeze.

I found out something new. I download the emacs tar ball and experimented with build options in order to see if I could find something where Emacs won't freeze. I did.

In the end font aliasing seems to be the cause of the problems. If I configure like this there is no freeze

./configure --without-all
--with-m17n-flt
--with-jpeg
--with-dbus
--with-freetype
--without-xft
--with-xpm
--with-xaw3d
--with-xiim
--with-libotf
--with-selinux
--with-gpm
--with-imagemagick
--with-x-toolkit=yes
--with-png
--with-tiff
--with-gif
--with-gsettings
--with-gnutls
--with-rsvg
--with-xml2
--with-gconf
--with-gpm

Observe that I have used without-xft. I have no idea what the solution will be as without aliasing things are more or less ugly.

One more observation. It seems that the freeze is dependant upon the font chosen in .spacemacs.

I had defined Lucida Grande Mono when the freezes happened. Changing this to DejaVu Sans Mono, and no freeze in README.org.

[manfredlotz]

I don't know how to pursue this bug. I have no clue if it is a bug in Emacs, Evil, Spacemacs or in the Lucida Font.

With last update, 105, emacs freezes during Ruby autocomplete. I launched Ruby console with C-c C-k as always

[manfredlotz]

I had the same today (also update to 105) with auto-comple and nim-mode. I think this is a new issue. It has nothing todo with the fonts.
