Things I've tried

akien-mga commented 4 years ago

No problem here on Mageia Cauldron with:

$ glxinfo | grep -i opengl
OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) HD Graphics 630 (KBL GT2)
OpenGL core profile version string: 4.6 (Core Profile) Mesa 20.1.7
OpenGL core profile shading language version string: 4.60
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.6 (Compatibility Profile) Mesa 20.1.7
OpenGL shading language version string: 4.60
OpenGL context flags: (none)
OpenGL profile mask: compatibility profile
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 20.1.7
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

"Intel" vendor means Iris, which is also the default driver since Mesa 20.0 IIRC.

Interestingly, when I try to force either i965 or iris with MESA_LOADER_DRIVER_OVERRIDE, I get super weird errors which don't make any sense:

$ MESA_LOADER_DRIVER_OVERRIDE=iris godot
Godot Engine v3.2.3.stable.mageia - https://godotengine.org
error: Kernel is too old for Iris. Consider upgrading to kernel v4.16.

libGL error: failed to create dri screen
libGL error: failed to load driver: iris
OpenGL ES 3.0 Renderer: Mesa Intel(R) HD Graphics 630 (KBL GT2)
...

$ MESA_LOADER_DRIVER_OVERRIDE=i965 godot
Godot Engine v3.2.3.stable.mageia - https://godotengine.org
libGL error: failed to create dri screen
libGL error: failed to load driver: i965
OpenGL ES 3.0 Renderer: Mesa DRI Intel(R) HD Graphics 630 (KBL GT2)

My kernel is 5.8.10 so the error is completing off.

These errors come from detect_prime.cpp @hpvb. Running with DRI_PRIME=0 fixes it:

$ MESA_LOADER_DRIVER_OVERRIDE=iris DRI_PRIME=0 godot
Godot Engine v3.2.3.stable.mageia - https://godotengine.org
OpenGL ES 3.0 Renderer: Mesa Intel(R) HD Graphics 630 (KBL GT2)

@Skallwar Do you still get the crash if you set DRI_PRIME=0?

@akien-mga Yes

@akien-mga ping ?

I suggest trying to upgrade to the latest Mesa version, and if that doesn't solve it, report a bug upstream to Mesa: https://gitlab.freedesktop.org/mesa/mesa/
