Has anyone tried running a GL application with a compositing window manager?  (e.g. xcompmgr, metacity, compiz...)?

It's needed to achieve trans(parent/lucent) windows on Linux.

I've managed to get xcompmgr running on my RHEL4 machine and it's working - I get nice fade in/out of windows opening and closing, however no GL application redraws properly - i.e. it renders initiially (<1sec) then no automatic refreshing.  It occurs with glxgears as well as my JOGL1.1.1 and JOGL2 ports of my application.  The only way to get it to refresh is through forced exposure events by moving a window over the canvas.

I know this isn't specific to JOGL but I assume someone else out there is using compositing window managers.
