Dear Maintainer,

I updated my debian unstable and GNOME desktop and GTK4 applications
(not GTK3) are hanging and crashing and unusable. I get these in dmesg:

```

```

I don't know what is the problem but I'm using Phosh temporarily and can
run GTK4 apps from terminal with `LIBGL_ALWAYS_SOFTWARE=1` variable.

I think the problem is not exactly from GTK4 or I915, but it's from crocus_dri driver from libgl1-mesa-dri package. I temporarily fixed this in my system with editing /etc/environment and adding `MESA_LOADER_DRIVER_OVERRIDE=i915` to the file.

Now I have some problem again. I can run GNOME Desktop with the variable but animations are not working even if enabled. Also Phosh desktop failing to run with all drivers, except with crocus:
