Horizontal lines appearing on my display (Ubuntu)
While working with my DELL XPS 13 laptop (shipped with Ubuntu), sometimes colored horizontal lines appear (I cannot recreate the beahvior, it seems random). I tried attaching an external monitor to see if the behavior pesists on the other monitor: nevertheless, it seems these lines don't appear anymore even on my laptop when an external monitor is attached.
I tried running a quick diagnostic test and no issue was found.
Any hint? See photo.
PC model:
Dell XPS 13 9320
OS: Ubuntu 22.04
Processor: 12th Gen Intel Core i7 1260Px16
RAM: 32 GB
Graphic: MESA Intel Graphics (ADL GT2)
Don't put attention on the info you see in the photo: they concern another post I was looking at, not my computer. I could take the photo in that moment as the issue suddenly appeared.

I took everyone's advice and downgraded to kernel 5.15 which seems to correct the issue. To make my life easier during system boot, I purged 5.19 using:
sudo apt purge
sudo apt autoremove --purge
I take it that everyone's SOP is to sudo apt full-upgrade?
For the short term, I'm going to be installing piece meal via the package manager.
I'll copypasta this on my Ask Ubuntu

Nice, this is a fix which I like more. I'll accept it as the solution. Please keep us updated on the Dell engineering's answers.

Please do keep me updated too, I'm currently on the `6.0.0-1012-oem` kernel and do *not* need the `i915.enable_psr=0` workaround, however I'd like to switch back to the 5.19 generic kernel when the workaround is no longer needed (as disabling PSR causes more display battery consumption, which would likely be quite noticeable for me with the 4K+ panel).

If you want to switch back to 5.19 generic kernel, now you could enable the "Developer Options" channel in "Software & updates", then do the "sudo apt dist-upgrade" to fix this problem.
Canonical has released fixed in 5.19 generic kernel, but now it's only available on Jammy-proposed, should be pushed to stable soon.

Now the fix has been ready in Canonical's 5.19 generic kernel and you could get the update by:
sudo apt update
sudo apt dist-upgrade
