Firefox 9 is jittery when Windows 7 display theme other than "basic" is enabled; how can this be resolved?


When browsing and reading web pages in Firefox 9.0.1, the second monitor I have attached to my laptop jitters and jumps. This is only resolved when I switch the Windows 7 display theme to the "basic" theme. I would really like to resolve this so that I may use other Windows 7 operating themes and Firefox, without the extra monitor becoming jittery. This problem does not occur with IE browser.

Please try disabling Use hardware acceleration when available and Use smooth scrolling (if enabled) in Tools (Alt + T) > Options > Advanced > General.

Yes, I have tried disabling hardware acceleration and smooth scrolling. This has not helped the problem. I also disabled all addons, and that did not help. Thanks for the suggestions, but I am still looking for a solution.
