Improper Thumbnail Display in Panorama


(Firefox Graveyard :: Panorama, defect)

7 Branch
Windows 7
Not set

(Reporter: peteklimek9, Unassigned)


Opened Firefox and switched to a different tab group by selecting the "Group your tabs" button. After the tabs in that group opened, I again selected the "Group your tabs" button. Some of the thumbnails in the just-opened tab group showed a graphic for the wrong site. I expected each thumbnail to show a graphic for the site represented by the thumbnail. The same behavior occurs for all tab groups.

This behavior began immediately after upgrading from Firefox 6.x to 7.0. I restarted Firefox in safe mode and the problem went away. However, disabling all my add-ons did not fix the problem. I found that disabling hardware acceleration fixed the problem. I also fixed the problem by re-enabling HW acceleration and toggling to False in about:config. Here's my graphics information:

May be a duplicate of bug 659278, but I thought the information about toggling the value of to False might be helpful.
It's indeed a duplicate. I will add the information about to bug 659278. Thanks!
