--- Comment #3 from kernel at mail.niknah.com ---
When I change the resolution or come back from suspend it flickers with random
dots.  https://youtu.be/9hXqSQjU080

It works again when I either switch the mode back to the old resolution or
press ctrl-alt-f8 & alt-f2

It's only a problem on the laptop eDP display, external usb-c display is ok.

In kernel 6.5.5, it goes away when I press ctrl-alt-f8 & alt-f2 or when I
switch the mode back.

In kernel 6.5.1, I couldn't fix it with ctrl-alt-f8 & alt-f2, it only goes away
when I switch back to the previous mode.
