Comment 5 for bug 998735

Hi,

I'm affected by this bug, but only when using cinnamon, not unity. Something was done in compiz to prevent this problem but this was not done in muffin/mutter.

I've found out that when using xscreensaver the issue happens as well, BUT when moving the mouse xscreensaver's password prompt shows up (with black background), and then goes away and blue comes back when the timeout expires, that sounds like some X buffer is turning blue, and xscreensaver is successful in overwriting it, while gnome-screensaver isn't.
