Tested previous xorg-x11-server releases. This regression happened between 126.96.36.1991-4 and 1.6.99-2 everything else (barring evdev) the same.
radeon here as well, latest rawhide.
I'll move it to xorg-x11-server
Specifically its caused by the fading. The same effect is achieved by running test-fade from the gnome-screensaver sources.
I'm going to go out on a limb and say that 'xgamma -gamma 1.0' fixes this, in which case it's a gnome-screensaver bug, not an X bug.
Yes it does, this to fix after the screwup. Thanks
$ xgamma -gamma 1.0
-> Red 0.100, Green 0.100, Blue 0.100
<- Red 1.000, Green 1.000, Blue 1.000
Yes, this is the workaround.

Similar, but probably different bug is bug 508397.

The problem is not fixed in gnome-screensaver-2.27.0-2.fc12.i586.
It's not a driver issue, I guess, since I have Nvidia card and I encounter the same behaviour.
Should be fixed in 2.27.0-9. Please test and reopen if not.
