Public bug reported:
Gnome 3 desktop
Multi-monitor setup with one screen rotated right into portrait mode
*Experimental* fractional scaling on Wayland with different scaling on each
monitor. Configured using:
~~~
gsettings set org.gnome.mutter experimental-features
"['scale-monitor-framebuffer']"
~~~
After wake from screen lock I often observe an "image" of an enlarged
rotated mouse pointer on the second (rotated) monitor which doesn't move
and doesn't appear on a screenshot. It overlays all other screen in
formation and cannot be erased by moving the mouse over the area.
Depending on where the mouse cursor was when sleeping it seems to appear
in one of two places, either towards the bottom left or top right.
After some time a block around the cursor image gets "corrupted".
This behaviour is not observed if logging in to a X11 session
Because this doesn't show up on a screenshot I have included a photo,
which also shows the monitor setup.
