Public bug reported:
I have a touchscreen ultrabook (Samsung Ativ Book 9 Pro)
With a dual-monitor setup, touchscreen inputs are scaled to the whole
desktop region rather than just the touchscreen display.
For example, with two displays (laptop on the left), touching the right
half of the laptop's touch screen registers as a click on the touchless
monitor. I expected the click to register where I touched the
touchscreen.
