Title:
Fullscreen videos and direct-rendering windows cause monitors with
integer-scaling to be reconfigured
Status in mutter package in Ubuntu:
Fix Released
Bug description:
- Enable fractional scaling toggle on x11
- Scale a monitor of 200%, 300%... (any integer value)
- Play a game or a video fullscreen
- The monitors are reconfigured causing a black window
This is expected in fractional scaling to make direct-rendering to
work properly, but not when the monitor is not scaled or scaled or
with an integer value
