I am also affected by this bug on my Lenovo laptop
I have an external monitor plugged in all the time, that means after the
display manager starts, the internal monitor is unusable (showing "snow"
and lines).
fixed this temporarily by booting 5.11 kernel instead of 5.13

Title:
[amdgpu] Random noise 'static' display after internal display turned
off/on
Status in linux-hwe-5.13 package in Ubuntu:
Confirmed
Bug description:
Laptop internal display shows random looking 'static' after it's
turned off and then on again. e.g. on suspend/resume, or when
plugging/unplugging an external monitor.
This appeared to come after a `dist-upgrade` took the kernel from
5.11.0-44 to 5.13.0-25 (hwe).
Others are seeing this with both NVidia and AMD graphics hardware:

I use i3 under gnome-flashback, but tried using default Ubuntu/Gnome
both X and Wayland, and gnome-flashback/metacity. All showed the same
problem.
Also tried an `apt install --reinstall xserver-xorg-video-radeon
libdrm-radeon1` for luck - no joy.
Running a 20.04.3 live stick the problem does *not* occur.
