Hi all

Run Lord of the rings online in windows mode taking up my main monitor.

Have Firefox 4 running on my 2nd monitor.

Occasionally everything works fine. But 9 times out of 10, all the drop down menus whether it's a book mark or me going into the top left firefox drop down menu, everything blank with the info flickering on for a millionth of a second every few secs.

I drag firefox to my main monitor, everything is fine, I drag it back to my second monitor, probs still there.

I close and restart and it's fine for a while (usually, sometimes it's still messed up) , then does it again.

Windows 7 64 bit pro sp1 Nvidia GTX 465 Main monitor running 1920x1200 2nd monitor 1440x900 Nvidia 266.58 driver

Worked fine with previous firefox version

Going into firefioxes options/ Advanced and Unticking "Use Hardware acceleration when available" seems to have fixed it.

FFX 4.01 on a ThinkPad R500 (ATI Mobility Radeon HD3470 ver 8.762.0.0) has the same problem. Disabling HW acceleration fixes the problem. It also fixes some Silverlight stability issues.

Same problem for me with ATI Radeon HD 5850. Fine on primary, flicker on any other. This occurs whether or not other programs are open on the Primary monitor. Displays *are* different sizes / resolutions: Pri=[1920 x 1080] Sec=[1280 x 1024]

I had Global Menu Bar Integration 1.0.5 Add On enabled. I disabled this and it moved my menu's off the Unity Bar and the Flickering has stopped.

I think I just fixed it here, go to options/general/browsing and disable use hardware acceleration when available. Hope this helps.

The solution is to disable hardware acceleration: 

Tools->Options->Advanced.

And de-select “use hardware acceleration where available”

Hope that helps

Disabling hardware acceleration fixes it for me me too, but it is slower. Maybe the acceleration code could be fixed?
