Bug description

when launching webcord, the following error occurs:

[13902:0410/112223.343310:ERROR:gl_factory.cc(128)] Requested GL implementation (gl=desktop-gl,angle=none) not found in allowed implementations: [(gl=egl-angle,angle=default),(gl=egl-gles2,angle=none)].

and the application does not start.

Additional context

I installed webcord via the AUR. This appears to affect both the latest release, webcord-git, and webcord-bin

Sounds like a GPU driver bug or use of experimental flags/optimizations. What's your GPU? Is GL driver proprietary (nvidia) or open-source (mesa)?

I would try running WebCord with EGL (OpenGL ES):

webcord --gl=egl

SpacingBat3 commented 1 year ago

Also, are you on Wayland or X11?

Thanks for your response!

I'm running on an Intel iGPU that I occasionally connect to a nvidia eGPU (so I have both drivers), but I encountered this issue while on mesa.

I would try running WebCord with EGL (OpenGL ES):
webcord --gl=egl

This output the following:

[3396:0411/085940.010741:ERROR:gl_factory.cc(128)] Requested GL implementation (gl=desktop-gl,angle=none) not found in allowed implementations: [(gl=egl-angle,angle=default),(gl=egl-gles2,angle=none)].
[3396:0411/085940.011756:ERROR:viz_main_impl.cc(186)] Exiting GPU process due to errors during initialization

as well as this popup:

This is on X11, I'll try it on Wayland as well.

On Wayland, it outputs the following:

[5654:0411/090531.012434:FATAL:gpu_init.cc(542)] Passthrough is not supported, GL is egl, ANGLE is

and what looks like the same popup as before:

Here's the result of inxi -G:

It looks like deleting windowState makes webcord launch now, but with the same errors:

[9788:0411/091412.573219:ERROR:gl_factory.cc(128)] Requested GL implementation (gl=desktop-gl,angle=none) not found in allowed implementations: [(gl=egl-angle,angle=default),(gl=egl-gles2,angle=none)].
[9788:0411/091412.574175:ERROR:viz_main_impl.cc(186)] Exiting GPU process due to errors during initialization
Cannot use import statement outside a module

That seems to have solved my issue though; thank you for your help!

It looks like deleting windowState solved the issue; webcord launches now without errors. Sorry to take up your time!

FYI this error meant WebCord was unable to read this file at all, so it was probably a permissions error (lack of read access?).

ah ok, so the GL errors were just a red herring. Thanks!
