Thanks for the bug report. Please try adding this kernel boot parameter:
i915.enable_psr=0
You can do that by editing /etc/default/grub and changing:
GRUB_CMDLINE_LINUX=""
to:
GRUB_CMDLINE_LINUX="i915.enable_psr=0"
Then save the file, run:
sudo update-grub
and reboot.
** Package changed: xorg (Ubuntu) => ubuntu
** Changed in: ubuntu
Status: New => Incomplete
** Tags added: i915
** Package changed: ubuntu => linux-hwe-6.17 (Ubuntu)
