### I have weird graphics glitches like the screen turning partially black.
If it seems like the issue described in [this thread](https://github.com/QubesOS/qubes-issues/issues/2399), try disabling the window compositor:
- Q -> System Tools -> Window Manager Tweaks -> Compositor -> uncheck "Enable display compositing"
