Thanks. Please try these fixes separately so we can see which one if any avoids the problem:

------------------------------------------------

1. Edit /etc/default/grub and change:

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

   to

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0"

2. Run: sudo update-grub

3. Reboot.

------------------------------------------------

1. Edit /etc/environment and add a line:

   MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0

2. Reboot.
