Bug Description
Binary package hint: thunderbird
Thunderbird has generally become very slow in Xubuntu Karmic Beta.
* Bringing Thunderbird to the foreground or sending it to the background takes 2-3 seconds. Switching between other applications is slightly delayed when a part of Thunderbird's window is visible.
* Opening a new message takes 4-5 seconds before it reacts to keyboard input
* Even simple message boxes (like the one that asks you if you want to save a message you're closing) take 2-3 seconds to appear.
* Sometimes (but not always), when bringing Thunderbird to the foreground, the message list or the contents of a message will appear, then disappear and load again.
* Sometimes (but not always) typing is slow when not at the end of the paragraph. Characters are displayed with a delay of 1-2 seconds.
Switching between other applications (OpenOffice, Xfce4-terminal, Thunar, Firefox...) is lightning fast, as usual in Xubuntu. In Jaunty or any previous version I ever used, Thunderbird did never have that problem.
Hardware: IBM Laptop Thinkpad T42, ~1.7 GHz, 700something MB RAM (usage during the test <50%), 3GB swap (only a couple of MB used during the test).
CPU load gets very high when switching from/to Thunderbird. The Xorg process (not thunderbird-bin!) uses 80-90% for several seconds. This is not at all the case when using other applications.
Anything I can do to help you find the cause?

Yes, it is terribly slow (x86_64 here). I finally decided to download the Thunderbird Beta 4 and just unpacked it in my home directory. Then I copied my .mozilla- thunderbird to .thunderbird. Needless to say, it rocks once again. I also had to download a nightly build of Lightning since I use that too.
