Comment 24 for bug 297143

Not sure if this relates to this bug or something new, but on a fresh install of karmic, whenever I open thunderbird, xorg almost grinds to a halt.

Thunderbird just needs to be open, It be doing absolutely nothing (my inbox is an IMAP box with IDLE enabled however).

Switching virtual desktops takes anywhere between 2-4 seconds! I can see redraws of any application's UI mostly and even just typing an e-mail message is slow and tedious.

Closing thunderbird makes my system return to normal operating speed.

(The same, though a little less slow, happens when running nxclient)

Both happen with compiz effects enabled and disabled, albeit when disabled it's less noticable.
