Description David Nolden 2007-09-29 09:40:09 UTC

When a game, for example nexuiz, reduces the resolution using xvidmode, the game window becomes only partially visible, because somehow the viewport seems to get messed up.

I'm using the current proprietary nvidia driver.

Since this does not happen when changing the resolution using xrandr, I've copied the solution in the attached patch from the xrandr implementation.

I have also noticed that the same problem appears in the xorg versions from ubuntu gutsy and opensuse 10.3 (I haven't tested earlier versions) when using twin-view setups.

This means:
When I have a big desktop over both screens, and start a game from there that changes the resolution, I end up hearing only the sound of the game, and have to switch to a terminal and kill the game to make the desktop usable again.

Has anyone noticed this? It is quite serious imo, and I've sent a patch..

Fixing component.

Is this still an issue for you?  Please send your patch to xorg-devel for 
review.
