Title:
Newly-introduced intel GPU bugs in 25.10 affecting Nautilus and other
applications

Status in linux package in Ubuntu:
New

Bug description:
I recently upgraded to Ubuntu 25.10 and discovered several issues I
believe to be related to recent Intel GPUs, which previously worked
flawlessly in 25.04 -- I'm using an Intel B580 GPU

I tested this on a LiveUSB to confirm it's not related to do-release-
upgrade; bugs present there too.

The most easily replicated of these is by simply opening the file
manager and moving the mouse around for a few seconds, which results
in pink, yellow, and blue rectangles being drawn on the file manager
(nautilus).

These issues also happen in e.g. file dialogs opened from a browser,
the new Terminal app, and sometimes the picture viewer. Some 3D games
that did not previously crash now do, but others do not.

Other applications (Firefox, VLC, VSCode) appear totally unaffected.

Furthermore, regarding nautilus, if you continue using it once it is
visually glitchy, a short time later it will freeze. It can only be
fixed by killing it from a terminal, then it opens okay again for a
bit. At that point, the dmesg log contains info about "xe device
coredump has been created" (bottom of dmesg log is right after I froze
nautilus, which I can replicate basically 100% of the time, from a
fresh reboot)

I have attached a dmesg log.

I also noticed a couple of lines in journalctl -f I saved (but didnt
save the whole log), which are possibly related, I'll paste those
here:

Oct 10 18:47:20 supercomputer org.gnome.Nautilus[25701]: MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:981: FINISHME: support more multi-planar formats with DRM modifiers

My attempts to remedy this so far have included updating motherboard
firmware and trying this mesa PPA
https://launchpad.net/~ernstp/+archive/ubuntu/mesarc which did not fix
the problem.
