*** This bug is a security vulnerability ***
You have been subscribed to a public security bug:
If you have a non-rectangular multi-monitor layout then the virtual
screen is rectangular, but only the parts visible on monitors are
blanked when you choose Lock Screen.
Steps to reproduce:
- Make a non-rectangular multi-monitor layout. (E.g., I have a 1280x1024 TFT
and a 1600x1200 CRT using the MetaMode "CRT-0: 1600x1200 @1600x1200 +1280+0,
DFP-0: 1280x1024 @1280x1024 +0+0")
- Move a window so that it's (partially) outside the monitor viewports yet
inside the whole virtual screen.
- Lock the screen.
- Connect to the computer using vnc or similar.
- Now, without having to unlock the screen you can still see everything that's
"outside" the normally visible parts. (E.g., in my case this is everything
that's in the bottom left 1280x176 area of the screen.)
