My system runs archlinux x86_64 with xbmc 10.1-11 (standalone) from the community repository.
I m using nouveau driver cause my graphic card is little bit out of date.
Everything works great except projektM. I can t discribe this problem proper, so i took some screenhots: (see attachment)
All settings concerning xbmc and projectM are default.

Are you still having problems with mesa 9.0 ?
Does the output differ when using llvmpipe/softpipe
Can you attach the dmesg and Xorg.0.log
