Hello all,
I have a HP Elite x360 1049 G9 2-in-1 notebook running fedora 38 with an Adler Lake intel video card.
After upgrading to kernel 6.2.13 (as packaged by fedora), I started seeing severe video glitches made of random pixels in a vertical band occupying about 20% of my screen, on the right. The glitches would happen both with X.org and wayland.
I checked that vanilla 6.2.12 does not have the bug and that both vanilla 6.2.13 and vanilla 6.3.2 do have the bug.
I bisected the problem to commit e2b789bc3dc34edc87ffb85634967d24ed351acb (it is a one-liner reproduced at the end of this message).
I checked that vanilla 6.3.2 with this commit reverted does not have the bug.
There is a similar regression reported on freedesktop gitlab tracker (by different reporter):
