Description
Here's is my X screen configuration. 1 monitor on 1 X screen, 2 on another.

The problem is wrong X screen is used for some windows. If I start Qt Assistant on X Screen 1, and right click, it works just fine on left size of the screen. On right side of the screen, right click context menus appear on the X Screen 0 instead.
This problem seems to be associated with trying to map X coordinates to QScreen.
This issue may be related to QTBUG-45485, as I've had windows appearing on wrong display at times.
I will investigate further.
