Description Matthias Bläsing 2009-03-31 12:38:49 UTC

Hey,

when I play a video via Textured Video and move the window onto the border between my two screens, I get the video splitted in the half and the two halfs placed onto the wrong sides of the screen. It beginns, when approx. 50% of the window are place on the second screen.

I'll attach a screenshot, that should explain it better. You can see the offset in the picture and the red line marks the approximate place, where the two screens touch.

Regards

Matthias

Please provide more info according to http://intellinuxgraphics.org/how_to_report_bug.html, like driver version and Xorg.0.log.

Are you using composite window manager like compiz?

Hi Matthias,

I just ran into the same bug, and also came up with a fix which I've posted here:

http://lists.freedesktop.org/archives/intel-gfx/2009-April/001994.html

If you want to test the fix, that would be great, (and please report back if it doesn't work for you).

Otherwise, I'll be closing this bug as soon as the fix lands in the repository. I do expect that the fix will be in the upcoming 2.7 release of the driver.

Thanks for your report,

-Carl

Just applied the patch to git version 375b2e40fcb17e94538a75392950e2533c1bb031 and it works as expected. I still have to test head, but yesterday head just gave me a white window.

Thanks for confirming the fix. It's in both master and the 2.7 branch now.
