Firefox Unresponsive Workaround #7 for Flashing Minimize, Restore, Close Buttons

PROBLEM

We had a lengthy discussion previously about the problem with Firefox 3.5.3 - 3.5.5 about the situation where Firefox Minimize, Restore, and Close Buttons in the window frame start to flash and Firefox becomes unresponsive. For long periods of time. There is more discussion about this problem here.


I found yet another workaround (numbered #7) for this problem. There are six(!) other workarounds presented here. I am curious how this workaround #7 works for your guys. We still do not have the solution.

I found this to be the least painful workaround so far. What you do when you have Firefox Flashing Buttoms on Vista or Windows 7:

WORKAROUND #7

Go Start/Control Panel. Go Systems and Maintenance, then Performance Information and Tools. Go Adjust Visual Effects in the left pane. Then under the Visual Effects tab, unselect Enable Desktop Composition and hit Apply. I bet it was selected originally! That's it, wait maybe 30 seconds. Blinking should go away. Now you can select Enable desktop composition again, hit Apply,  and wait another 30 seconds. No more blinking with fancy windows.

THIS WORKAROUND WORKED FOR ME, WHAT ABOUT YOU?

Let me know in the comments below if this worked for you. It is the quickest and least destructive workaround yet.
