ubuntu 22.04, AMD 7840, SCREEN turn white/black/stripes
My screen suddenly turned completely white, then only the bottom half was white, but I can still operate the application window. When moving the application window, the bottom half of the screen turns the Ubuntu theme color.
Only lock and unlock the screen or turn off the screen can fix the situation.
I report the bug to Ubuntu also, there are more logs and information in the link: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2042054
