There’s a GitHub issue that describes graphics artifacts where the image is being redrawn. The problem there seems to be with the Intel GPU, but it may still be worth a try (run as root and reboot):
[user@dom0 ~]$ sudo -i
[root@dom0 ~]# cat << EOF > /etc/X11/xorg.conf.d/99-intel.conf

### Qubes OS release
Qubes R4.1 current-testing
### Brief summary
CPU… : Intel i9-12900K
I'm using integrated GPU Intel UHD Graphics 770 as my display source.
After updating kernel-latest to the version 5.17.7 and booting Qubes with it I'm getting graphics artefacts in places where the image is being redrawn. This problem is present starting with LUKS password input stage.
The kernel version 5.17.5 works fine.
I've checked logs but didn't see any errors or difference compared to the kernel version 5.17.5.
I've tried bare-metal debian with kernel 5.17.6-1 from sid repository and there is no such problem.
When kernel 5.17.7-1 will be available in sid repo I'll try again.
Maybe it's upstream bug.
### Steps to reproduce
1. Update kernel-latest to version 5.17.7.
2. Boot Qubes with kernel 5.17.7.
3. Observe graphics artefacts.
### Expected behavior
No graphics artefacts.
### Actual behavior
Getting graphics artefacts in places where image is being redrawn.
