I can confirm this bug on Kubuntu 8.04 using KDE 3.5.9. I recieved the same problem, I recieved a window deceration error then lost my window decerations on Thunderbird. When I set desktop effects back to none I got the Thunderbird decerations back.

I was using Extra visual effects. I have not tried over an extended portion of time, but for the moment Thunderbird is working normally under None in visual effects. -- Missing window decoration in Thunderbird with Visual Effects on in Hardy https://bugs.launchpad.net/bugs/207576 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
