I have the same problem since upgrading to Ubuntu 9.04. The problem apears when I have more then about 5-6 windows in the same workspace, but not always.
Glxinfo reports: direct rendering: Yes server glx vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) G45/G43 GEM 20090326 2009Q1 RC2 x86/MMX/SSE2
I'm running Ludovico Cavedon patched mesa from here https://edge.launchpad.net/~cavedon/+archive/ppa to get a virtual screen size bigger then 2048, so I'm running dual screen.
