If this would be possible compiz could add itself as video adapter and the video players would not need to be changed.

That's another odd observation. compiz does not report about a missing stencil-buffer on my system (GeForce7900GT, 1.0-9755 driver). All errors I get at startup-time are these: compiz: Failed to load slide: freedesktop compiz: video: no 8 bit GLX pixmap format, disabling YV12 image format Best regards...

I found some issues with the decoration plugin as I was integrating your patch. There's still some issues but it should be better now. The decoration matching option I added only allow you to disable decorations for currently decorated windows, in the same way an application can request that a specific window shouldn't be decorated. There's no way to disable shadows for windows that are currently not decorated through this option. I thought that it would be best to provide this functionality through an additional matching option. I just added and pushed out such an option. E.g. disable shadows on dock windows by setting this new shadow_match option to: "!type=dock" - David ___ compiz mailing list compiz@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/compiz

There's currently no way to get decorations blurred but not the shadows without a stencil buffer. Blur plugin should output something like "No stencil buffer, region based blur disabled" if this is the case. There seems to be some other drawing artifacts in your videos, which might be a bug that is exposed only when stencil buffer bits are not available. - David ___ compiz mailing list compiz@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/compiz

[compiz] compiz segfaults using apps using gtk with kde
Hi, a bug introduced in the last two days seem to have made its way in to git, it very often segfaults when playing around with gtk-apps such as gconf-editor and screenlets when using kde and kwd. Or is this a local problem? Regards ___ compiz mailing list compiz@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/compiz
