Description

Created attachment 6629 menu item vertically shifted towards primary monitor

I have three monitors set up with the left and right monitors slightly higher than my primary laptop in the centre.

When clicking on a menu item on the left hand or right hand monitor the menu item is lower than expected. It is appearing at the height of the primary monitor in the middle.

This happens in multiple applications, but not all of them. The application shown in the picture is a basic JavaFX application.

I've attached a picture.
