The amdgpu driver occasionally suffers from graphical glitches/screen
corruption when the screen goes from being static to something changing. The
graphical glitch appears on screen very briefly, for around 1 frame. This most
often happens when I scroll or move my mouse in an application like Firefox or
Thunderbird and it ranges from occurring every few seconds to every few minutes
or hours (usually once every ~30 minutes). There is no output in dmesg when
this occurs.

Using the grub option amdgpu.dcdebugmask=0x10 fixes the issue at the expense of
battery life.
