It seems this bug occurs because of a bad interaction between Thunderbird and the overlay scrollbars. (If you aren't sure what I mean by overlay scrollbars, see this screenshot -- http://4.bp.blogspot.com/_1QSDkzYY2vc/TXAXguJ5WdI/AAAAAAAADS0/9205Attwbhc/s550 /unity-overlay-scrollbars.png -- you've undoubtedly seen them.)
If you remove all the overlay-scrollbar packages (overlay-scrollbar and liboverlay-scrollbar*) your Thunderbird scrollbars will start working again. Even better, your other applications will be back to having normal scrollbars again. It is possible (apparently, I haven't tried it) to turn off overlay scrollbars for individual applications. If Canonical are determined to keep the overlay scrollbars in general, please at least turn them off for Thunderbird, then this annoying and long-standing bug can finally be closed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1025935 Title: Thunderbird 14.0 scrollbars have a wrong background [regression] To manage notifications about this bug go to: https://bugs.launchpad.net/light-themes/+bug/1025935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
