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.
