FWIW, I tried with 24 and 16 bpp, with and without the composite extension enabled and it worked fine in all cases. You may also check (or post) the output of `xdpyinfo` on that server.

Disabling XRender *and* XShape would work. But most gtk apps are not rendering well either in that setup so I am not sure that would take us very far.

Not a bug in xfwm4.
