Public bug reported:
an interesting amdgpu issue:
I currently have two external monitors, and only one will display the
desktop at a time - the other is completely white. The interesting thing
is that with each interrupt that the kernel receives from keyboard /
mouse, the screens will flip which one is visible. With my monitors
positioned above and to the left of the laptop's built-in display, the
flashing monitors feel akin to attending an electronic light show, or
perhaps a display of fireworks - the monitors flip visibility with each
keypress.
