Public bug reported:
When the mouse cursor leaves one of the screens, there is either :
- no problem
- the screen becomes black just below the position of the cursor and
instantly comes back to normal.
- the screen becomes entirely black with some random colored pixels
flickering on the far left of the screen. I have to move the cursor to the
black screen, otherwise it stays black.
