Mutter showing window backbuffer after screen plugged/unplugged
I have an external monitor connected to my laptop. It's at a scale factor of 1 and when it is connected the internal screen is turned off.
When I unplug that monitor the internal screen turns itself back on. The internal monitor has a scale factor of 2.
If I have a nautilus window focused when that happens, the compositor appears to start showing the back buffer of that window.
This is on wayland with mutter 3.32.2.
