Bug 480420

SUMMARY
***
Mouse cursor is not visible on secondary screen. I can still interact with the windows placed there, interact with the taskbar, make selections on the desktop, but I don't see the mouse cursor. I am using a laptop with an external monitor, and the screen affected somehow is always the laptop's built in screen, even if I make that as the "primary" screen. The external monitor always has a mouse cursor.

The external screen is a 4k Dell monitor connected through a thunderbolt docking station, and the built-in screen has a resolution of 3840x2400. I normally use a scaling of 150% on the external screen and 200% on the laptop's built-in screen, but setting both to 200% does not fix the issue. If I disable the external screen altogether, then the built-in screen shows the mouse cursor. But when both are enabled, the built-in screen will not have the mouse cursor no matter what.

I am on Arch Linux with the KDE-Unstable repo enabled, and otherwise up-to-date.

STEPS TO REPRODUCE
1. Have a laptop with an external screen,.

OBSERVED RESULT

No mouse cursor is visible on one of the screens when the mouse is moved there.


EXPECTED RESULT

The mouse cursor should be visible on both screens when moved there.
