Error starting frog on Fedora 36 - No provider of glGetShaderiv found.

[brpaz]

Hello. I installed From from Flatpak in a recently updated Fedora 36 install, but when I start the application, it crashes with the following error:

libEGL warning: MESA-LOADER: failed to retrieve device information

libEGL warning: DRI2: could not open /dev/dri/card0 (No such file or directory)
libGL error: MESA-LOADER: failed to retrieve device information
Cache downloaded codes: ['eng']
No provider of glGetShaderiv found.  Requires one of:
    Desktop OpenGL 2.0
    OpenGL ES 2.0

I found out some Reddit thread of a similar problem regarding GTK4 apps and they said to run with GSK_RENDERER=cairo environment variable and it works.

This error only apps in Frog and not other GTK4 apps.

I seem to have OpenGL installed:

I'm on Fedora 36 from beta and still have no issues like these. Do you use an Intel card? Please look at #53.

Yes, I have an Intel card. I found a user with exactly the same problem on Reddit - https://www.reddit.com/r/archlinux/comments/v2qrjf/mesaloader_problem_to_run_flatpak_app/ and the solution worked.

I needed to give dri permission to the Flatpak for it to work.

Maybe this should be documented somewhere.

I'll add it to the next release. But for now, I'm glad you found a solution.
