SUMMARY
This one is really best explained with a demo - https://www.youtube.com/watch?v=56xy9p0wPqM

Seems like there is two bugs at play, one is that when dragging a widget from one screen to another, it loses focus on the widget 100% of the time and has to be picked up again to continue dragging it.

And the bigger one, when the first bug happens, widgets get stuck BEHIND the edge of the screen, making them 1-pixel visible or completely invisible


STEPS TO REPRODUCE
1. Multi-screen setup required
2. Drag a widget from one screen to another
3. One or both above described bugs get triggered

OBSERVED RESULT
Widget loses focus when dragged across a different screen and sometimes gets hidden next to the displayable screen

EXPECTED RESULT
Widget remains movable and doesn't get stuck in a void behind a screen
