This sounds similar to an issue that I commonly have, only it's not reliably producible and affects the entire desktop. In my instance, compiz will stop updating any window on the screen, until I move the cube or move the window. This usually starts working after a force kill of compiz and a restart of compiz.
This seems to be related to compiz's rendering system, where it gets caught in a loop/segfault somewhere, although I haven't done any debugging to narrow down the problem.
