My desktop is 1400x1050. Attached is a png that causes X to reliably hang the desktop with XAA (no xorg.conf), radeon.modeset=0 and compiz (opening by double clicking the png on the Desktop, which opens eog). The png is 1400x1050. After the hang the display is totally unusable, but I can ssh in. Stopping and starting gdm has no affect.
After rebooting and enabling EXA (using radeon.modeset=0 and compiz), X does not hang, but is painfully slow, as mentioned in bug #513956.
As a side note, if I logged in with EXA but without compiz, started firefox and then tried to enable compiz, I could not ("Desktop effects could not be enabled"). I had to close firefox first to successfully enable compiz. There was nothing interesting in dmesg or Xorg.0.log to try to debug this.
