Comment 82 for bug 1958191

I'm unsure if this is really fixed in Jammy

I'm seeing flickering with 5.15.0-41 as well which seems to improve with i915.enable_dc=0 intel_idle.max_cstate=2

cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-5.15.0-41-generic root=/dev/mapper/vgubuntu-root ro quiet splash i915.enable_dc=0 intel_idle.max_cstate=2 vt.handoff=7
