Godot 3D Viewport not working correctly on my Linux machine

[yohannes-jo]

Godot version

3.5 stable

System information

Linux Mint, X11, GLES2/3, Intel HD Graphics 605

Issue description

Any mesh instance I add to the project ends up being black, sometimes it works but then when it doesn't, it won't work again for an unspecified amount of time.
This problem extends to the runtime, 2D viewport works perfectly fine though.

Steps to reproduce

Open a new/old project

• open a 3d scene
• create mesh instance and give it a shape (or resource, both end up the same way)
• that's it

Minimal reproduction project

No response

Didn't add a reproduction product since I'm writing through my phone at the moment, really sorry.

Does setting 2d size fix it? This is probably a duplicate of #55471

Since I'm using 3.5 stable, the renderer is GL, not vulkan
The 2D viewport works just fine, along with every node under it, it's just something with the mesh instances

Ah my bad, I didn't realize this is about 3.5

Related to #25512, which occurs on Windows. The Windows Intel driver's codebase is entirely separate from the Linux driver, so rendering bugs aren't expected to be shared across platforms on Intel.

@yohannes-jo Do you have any lights in your projects? Also, please upload a minimal reproduction project to make this easier to troubleshoot.

Yes, I do have lights in my projects. The problem doesn't stem from the lighting, it stems from the fact that every other time I open the editor, alongside the viewport, the meshes appear black unless light is reflecting off of them.
I would've assumed that happened as a result of lack of light (or a different implementation of it from GLES2, the one I use now as it works just fine) but it only happens half the time. Same with the exported or debug version of the project.
I will be sending a demo project now.

I'll also be sending the occasions where it does work and when it does not. (it is not consistent at all)

**screenshots of the occasions, viewport usually doesn't glitch out until it gets re-opened, but the debug program is a roulette, you won't know what will happen whenever its opened/closed.

Half of the screenshots are the ones when it works as it should, and the rest are when it becomes pitch black.

@Calinou here are the required files and descriptions. Sorry for the late reply.

Didn't notice it, will do.
Update on the issue: it seems to be only happening on GLES3, 2 works just fine.

But that disables a couple of good features so if there are solutions to this, much appreciated.

Duplicate of #43891. This is the same Intel GPU generation (HD 600 and HD 605), so the bug is likely due to the same cause.
