SUMMARY
When performing an action that changes the cursor it stays stuck in that state and doesn't return to normal. The cursor only stays stuck within the contents/boundaries of the window of the application. Moving the cursor outside the window of the program makes it return to normal, but moving back over the affected program window makes the cursor get stuck again.

STEPS TO REPRODUCE
1. Perform an action with the cursor like drag-and-drop in Dolphin or on the taskbar.

OBSERVED RESULT
The cursor stays and gets stuck as "dragging hand" or "stop sign" or whatever action performed. It stays stuck within the area/window of the program (e.g. Dolphin or taskbar). Cursor acts like normal outside of the area/window of the affected program, but when the cursor moves back over the area of the affected program it returns to the wrong stuck state again (e.g. "dragging hand" or "stop sign").

EXPECTED RESULT
Cursor state updates normally.
