Quick update, I tried installing Thunderbird from the Mozilla Daily PPA (version 3.0.7~hg20100808r4894+nobinonly-0ubuntu1~umd1~lucid I believe), that didn't solve anything, the same problems are still there.
I've also installed 3.1rc2 from Mozilla's website (as suggested by Lucazade on the forums), and that works, no visual artifacts and I could install Lightning. So that's a temporary workaround for those interested. -- Thunderbird menus and dialog boxes are blank https://bugs.launchpad.net/bugs/615779 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
