Taking that into account we should use the main screen's height in order to calculate the correct vertical offset of the window - even if coordinates are physically on the secondary screen, otherwise on screens with different height that are not aligned along the bottom border we will have a wrong vertical position.

Right.  Both scenarios are intermittent and relatively hard to reproduce, cosmetic, and recoverable simply by moving to another screen.
The scenario described in the ticket is fixed.
