(Get the code!)
It seems to be caused by fractional display scaling: The display is configured to use 150% scaling.
When the scaling is set to 100% (native DPI), mpv and Firefox can play the video in fullscreen without triggering the bug, everything fine just like it should be.
When the scaling is set to 200%, there's another bug: The player goes to fullscreen without flicker or framebuffer changes, but only plays the video in the upper left quarter of the screen. The other three quarters are not updated and keep the buffer data from the point where the fullscreen was invoked.
