Bug 513778

SUMMARY
Since recently there's a reoccuring issue. After waking up my system or using `Alt Tab` to switch between windows or switching between virtual desktops (I'm not sure exactly what triggers it), a program can become entire unresponsive to my pen tablet cursor an inputs.

The cursor style (arrow icon or otherwise) will not update. It keeps looking exactly like the cursor that from the desktop or other window that is still responding to the pen tablet.
Some programs like Blender fix themselves easily by using `Alt Tab` again. Other apps like Dolphin can remain unresponsive until they are closed and opened again. I've also seen it happen to more programs, so it might be a general issue?


STEPS TO REPRODUCE
Unclear. Keep programs open and use the pen tablet as the main input until one of the windows "breaks".
I'm still trying to find out how to reproduce it reliably.

OBSERVED RESULT
No pen input (pressure, and side buttons) are registered by the program anymore. The header of the window does through. It can be moved, resized, closed, etc.

The style of the cursor (icon) is stuck on whatever it looked like on the previously active window.

EXPECTED RESULT
Any program should be responsive to pen inputs all the time.
