test case: g++ -o test-ui test-ui.cpp `pkg-config --libs --cflags clutter-1.0` -Wall; ./test-ui
With the attached sample clutter test-application I'm getting following error on the terminal I started the X server:
(EE) DoSwapInterval: cx: ..., GLX screen = ...
... and the output of the application is attached, also.
The problem occurs only with the radeon driver. I can not test, whether the stable radeon drivers are also affected.
My system is a X86 gentoo with xorg-server, libdrm, mesa, xf86-video-ati and all the needed dependencies from the current git repositories. Kernel: 2.6.31-rc5.

"black boxes" instead of well rendered characters

Xorg.log (as you can see, I'm using radeon KMS)
I just rechecked the test case application within an openbox - non AIGLX - environment and there the text is rendered correctly.
So the error seems to be origined in the mesa/3D backend I think, when it only occurs with compiz running.
