I have a laptop with Ryzen 5500U running Ubuntu 20.04 with the latest-ish Linux kernel (5.13.13). Settings reports "AMD Renoir" as the graphics settings.

Whenever the laptop wakes from suspend, I get just animated "static" on the screen (like $ cat /dev/urandom > /dev/fb0). See photo.

I can't find the right keywords to search for this, anybody with experience?
