Description Thomas M. 2007-08-31 03:07:22 UTC

Xorg version : 7.3RC1 (xserver-xorg debian package version 1:7.3~rc1)
Radeon driver version: 6.7.192 (xserver-xorg-video-ati version 1:6.7.192-1)
Xrandr utility version found in debian package x11-xserver-utils version 7.2+3.
I'm using a ATI Radeon "ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]".

When the screensaver starts (xscreensaver version 5.03) only one portion of the screen is blanked. This started after I upgraded to the recent version of xserver-xorg-video-ati. 

The blanked part is a 800x600 pixels rectange at the top left corner while my screen resolution is 1400x1050. 

I suspect that this might be related to randr which happen to show my S-video output at 800x600:

xscreensaver has fixed a number of bugs with RandR since 5.03 - it decides
what part of the screen to cover with it's "full screen" windows, so this
is most likely a bug on it's side, not Xorg's.
