Comment 1 for bug 217434

I can confirm this bug. It didn't happen until I did a clean install today and installed all the updates. When I enabled the shift switcher plugin in compiz-fusion (compizconfig-settings-manager), the screen just goes dark when I try to tab through the windows. The windows do switch (one tab brings up a different window), but the actual visualization is blank.

Any idea on how to troubleshoot this?
