Description Ross Burton 2008-07-30 02:09:19 UTC

My laptop booted X at 1024x768, I then connected an external monitor and randr'd to 1680x1050.  Now whenever I move a GL application out of the top left 1024x768 pixels, it stops drawing.  It appears that the GL driver still thinks that the screen clip region is 1024x768 and not 1680x1050.

Debian sid, -intel 2.3.2-2+lenny1 (2.3.2 with some 2.4 patches cherry picked)

Please attach xorg.conf, Xorg.0.log and xrandr output, according to http://www.intellinuxgraphics.org/how_to_report_bug.html

Ross, does this still happen with 9ec36e0c8bd8a4bd7c40569412fc1a21219b5af9 and 22918f62c89a4314fb5d01c58f22fee5b9a15a27 applied from git master?  Those update the SAREA bits even with the pipe A quirk on, but I'm not sure if that applies to your machine...

Feedback timed out. Please reopen if you still see this with the latest driver and provide the required info. Thanks.
