Created attachment 25560 [details] Screenshot showing 3D being rendered over top of another window which has the focus Since upgrading to Ubuntu Jaunty, any 3D window is drawn over top of all the other windows. Also when the 3D window is moved, minimized, closed etc. it leaves behind an image where it was. I've tried changing several options in xorg.conf including EXA vs. XAA.
This is a limitation of DRI 1. disable compiz or desktop effects to avoid this.
This happens for me with and without compiz enabled.

I'm using metacity but there are no fancy fading effects or anything like that.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=524794 . My theory is that apps tend to select the 32 bit ARGB visual with current versions of xserver and Mesa, resulting in automatic compositing of the GLX window. In theory running affected apps with XLIB_SKIP_ARGB_VISUALS=1 should work around it, but there's a libGL issue which may cause apps to fail to find a visual at all. I'm working on getting that fixed.
