Only happens on external monitor; occurs more often when shake cursor effect is turned on. Using a dual gpu system with intel igpu and nvidia dgpu. I think this is a recent regression.

Can't reproduce at all on my neon unstable system on the same machine. So maybe this is caused by the nvidia driver version? On arch I have 545.29.06.
Git commit bb8b51a3abe750a42907f393bc35da5f5d034a83 by Vlad Zahorodnii. Committed on 20/02/2024 at 23:01. Pushed by vladz into branch 'master'. Fix disappearing software cursor in overview and zoom effect The overview and the zoom effect repaint the whole screen every frame. But the problem is that there are cases when there's nothing to repaint. I'm not quite sure why it happens. Maybe overview and other effects should honor the repaint region, but on the other hand, they don't need to because of the fullscreen effect api promises. This change forces overview and zoom effect to use "generic paint" code path in the workspace scene to force infiniteRegion() repaint regions.
