Window doesn't position as expected with multi screens

Set multi screen environment. Main screen on right and other screen on the left side.
Create Quick or Qt Widget application.
Launch Application in Left window.
Set application X position to 100.
Expected: Application is moved to 100 pixels from left screen left side.
Result: Application is moved to 100 pixels from right screen left side.

Behaviour is happening because left screen has negative x-value. Main Window has position (0,0). That's ok. Problem is that it's expected that window position is mapped to the whole desktop geometry including all screens. Not to one screen geometry.
