Public bug reported:
When running on dual screen config, the cursor is heavily flickering.
Makes it a very unpleasant experience, if not renders it unusable. If
switched to only single screen, cursor is completely stable.
When issuing
xrandr --output HDMI-2 --scale 0.99x0.99
again cursor is stable. Switching to 200% scaling in the desktop settings,
doesn't help.
I tried to catch the effect in a movie. However, because of frame rate,
it is not possible to show the effect. If if its helpful, let me know
and I'll try harder.
