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?
