thunderbird redraws constantly, forcing compiz to redraw the screen constantly

[Daniel van Vugt]

thunderbird redraws constantly, forcing compiz to redraw the screen constantly.

Running the Compiz Benchmark plugin I noticed my screen (which looks idle) is redrawing constantly at 50-60 FPS. Minimizing thunderbird stops it. And idle screen should result in the Benchmark showing almost zero FPS.

At the same time I notice thunderbird is at 100% CPU.

Restarting thunderbird fixes both problems.
