[nvidia] Launcher graphics corruption with nvidia driver

[Teo]

I have disper installed and often use "disper -s" and "disper -S" to switch between laptop screen and external screen (a shame that there's no native way to do it, btw).

The screenshot shows how the Launcher showed up after a switch (look at the left side of the screen: that's the launcher). Hiding and showing it again didn't fix the issue. Switching screen back and forth did.

Other times, after a switch, some windows are black and only redraw when you click on or move the mouse over them.

Status changed to 'Confirmed' because the bug affects multiple users.

Also, one more thing, could you try removing the Nvidia drivers from the "additional drivers" dialog and testing to see if this happens again with the open source 'nouveau' driver?
