I have a dual monitor setup, main is a Lenovo Y710, secondary is an old ViewSonic (about 14"). When I am viewing a Youtube video in fullscreen mode (Youtube's fullscreen, not the f11 Firefox fullscreen mode) and then I click a Firefox window on my other monitor, the form elements of the window become nonresponsive. Ie, I get a "not responding" message in task manager, the cursor changes to a swirly circle, and the window doesn't paint the elements of the form (it gets a haze over it).

Reproducible: Always

Steps to Reproduce:
1. Have two monitors
2. Open firefox on both
3. View a Youtube video on one of them, in fullscreen mode
4. Click on the other monitor
5. Click back onto the first monitor, with the fullscreen video playing
6. Profit!
Actual Results:  
Firefox's visual elements no longer repaint to teh screen. I can still minimize and maximize the window, and it still streams data (ie a song still plays), so it's probably a threading issue. Hey, are you guys hiring?

Expected Results:  
It ought to play nice with other programs (and itself) and let me click in other windows.

kbrosnan, in the mozilla chat on irc.freenode.net was very polite and helpful. It is my understanding that, as a reward for submitting a valid bug, I was to be awarded three wishes. My first wish is for endless riches. My second wish is for kbrosnan to be awarded a nice hat, one that is stylish enough to be noticed, but in keeping with his/her particular aesthetic. I reserve the third wish for a future point in time, when I shall redeem it as needed.

Can you still reproduce this bug in Firefox 6?

Please update to Firefox 6 or later, update your plugins, and retest in a new profile. If you still see the issue with the updated version of Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME.
