blender3d vs compiz (ATI running Envy drivers)

[joaoramos]

hey folks,

everytime I run blender3d on my ubuntu 7.10, compiz-fusion overlaps the desktop over it (I guess). if I want to perfectly run blender3d, I have to shut down compiz fusion, as if my ubuntu desktop was in a higher layer and blender3d was behind it. I'm portuguese, so I'm sorry for my bad english. any help?

Any driver that currently uses Xorg's DRI (ati, intel, fglrx) will have problems displaying other opengl applications at the same time as compiz. This is due to a limitation in the DRI, which does not properly support direct rendering of redirected windows. For more information: http://bugs.freedesktop.org/show_bug.cgi?id=8732 , http://dri.freedesktop.org/wiki/DirectRenderingToRedirectedWindows

DRI2 is designed to resolve this issue, and is in the testing stages for intel cards. Even after it's completely, you will have to wait for AMD/ATI to update their drivers for DRI2 as well.

Speaking of which, any information on when the Intel implementation will make it into the official branch? I'm not one for patching my display drivers...
I know it's only been like 2 weeks since krh made his plans known on the mailing list...

Sorry, you'd probably have to ask the Xorg/DRI developers to find out.

You can always run "blender -w" to get it in windowed mode.

I get the opposite problem in fullscreen mode with nVidia using the standard restricted driver. I actually get Blender with no titlebar and the panel going over the application.

Hmm, I get the same problem with blender that you do, the no window border/title bar "it's just full screen suck it up" thing. Running "blender -w" doesn't help. Any other reason why blender is the only app that compiz doesn't wrap a border around?
