Further trying to help narrow down: I have Mesa 22.0 here and things
work fine, but my GPU is different (Intel HD Graphics 520 SKL GT2),
so this points towards either device-specific code, or towards the
Mesa driver chosen by the Mesa loader.

Note that there are two drivers: the traditional “i965” and the new
“iris” driver. Here I am using “iris” (and there is not even the other
installed).

You can set “MESA_LOADER_DRIVER_OVERRIDE=iris” if your GPU is supported
by the new driver and if things then work that will mean that the issue
is most likely the i965 driver. Alternatively, if Iris driver does not
support your GPU but Vulkan is supported, you can try the “zink” driver,
which implements OpenGL and GLES on top of Vulkan (and again, if that
works, then there is some bug in the Intel driver you are using :D)

I hope this helps!
