It seems most appropriate to post my screenshots of Ubuntu Linux 9.04 with Compiz-Fusion right now right after replacing Windows 7 Beta 7000 with it. I went through and turned on quite a few custom effects, including my windows burning up when they are minimized or restored.
I suspect that it’s having all these animations and effects on that make the WordPress editor terribly unresponsive. Or it could be something completely different since CPU utilization only spikes when I interact with the windows.
