[SOLVED] Kernel 6.10.x artifacts on native display - Dell XPS 16 9640

Since upgrading to Kernel 6.10.1 I'm getting graphical glitches as in the picture right away when the booting starts and they persist all the way to the wayland graphical session (with Gnome on top).

The issue shows only on the native display. Other displays connected via either DisplayLink or directly via HDMI dongle work without glitches.

The latest working kernel is 6.9.9.arch1-1.

Not sure what more info I can provide. Did somebody get similar problems?

I had the same and made a topic about it, you can read about it here: https://bbs.archlinux.org/viewtopic.php?id=298071

Basically you should add

i915.enable_psr=0

to your kernel parameters until a fix in the kernel is added.

If you want to know how to add kernel parameters check out the wiki: https://wiki.archlinux.org/title/Kernel_parameters

Thank you! Worked like a charm.

Somehow I didn't find that topic when looking for the issue.
