Bug 483527

SUMMARY
The visual and actual cursor position is misaligned horizontally or vertically. Usually, this happens, when a window is moved to the left side of the screen, creating a vertical split with META+ARROW LEFT.

This bug is noticed since the update to plasma 6, unfortunately I don't know what part of plasma it causing it. 

STEPS TO REPRODUCE
1. Move the Firefox window to the side of the screen with [META + ARROW LEFT]. (splits the monitor horizontally and moves the active window to one side)

OBSERVED RESULT
This Bug happens not always, but frequently.
- The cursor gets misaligned on the window that was moved.
- When a second split window is on the other side, the bug applies to that too.
- Most times the misalignment is a fixed horizontal distance as marked "x" in the image, (I don't know how to clip the pointer);
- Sometimes there is also a vertical misalignment with roughly similar distance.
- This is most noticeable on buttons, but applies to all elements (grabbing the top bar to move the window, double-clicking to maximize, hovering links, elements in the debug window)
- The visual cursor position is always down and right of the actual position.
