Bug 491956

SUMMARY
When you change the resolution of your screen, the touchscreen does not change with it.  This causes you touches to be places you are not expecting.
Note:  This does not happen when you re-scale your display, only when you change the resolution.

STEPS TO REPRODUCE
1. Start with a normal Plasma 6 install on a machine with a touchscreen.
2. Change the resolution.  Possibly most important, change the aspect ratio (16:9) -> (5:4)
3. Try touching things, especially things not in the center of the screen.  I have found that using the onscreen keyboard is the easiest way to see this, because it highlights the keys that are pushed.  But it is not related to the keyboard.

OBSERVED RESULT
Depending on how dramatic the resolution change, and how far off center (both horizontal and vertical) I am touching, where I am touching, and where my desktop thinks I'm touching can be wayyy off.

EXPECTED RESULT
The desktop should think I am touching where I am touching.
