This bug only occurs after clicking/activating compiz via "Compiz Fusion Icon". After I enable compiz, the taskbar acts weird and doesn't redraw.
Here's an example screenshot, the first app I open will always stay the green active application in the taskbar. No new windows that I open show in the taskbar, although the taskbar is still clickable except with no animation. Notice the Terminal's that arn't showing in the taskbar.http://img1.us/i/HRGl4.png
