How do you circumvent this problem in java2d? The screen turns completely black and is not recovered until the game is closed and opened again, everything else works apparently. This is not just on CTRL-ALT-DELETE. If the OS promots a UAC action (“Do you want to run this program in admin” etc) for any other programs the same problem happens. I am guessing the swing thread dies.
Sounds like a driver bug to me.

Seems to be, I just checked and the EDT is alive and the buffer not lost. HD7870 with newst Catalyst. Gonna check tomorrow if reproducable on other computers.
