>From the comments above it looks like there could be several distinct causes of Thunderbird running at 100%.
In my case, I have just upgraded to Raring and the situation has got worse. It now happens pretty much every time I try to minimise or close Thunderbird. Thunderbird will just sit there for hours running at 100%. For me it's worse than that because I use ibus to switch languages and it causes ibus to refresh itself continuously too (see bug #1162008), thus making the computer practically unusable. My key observations are that: - Now I have upgraded to Raring, this 100% cpu usage is (sometimes) happening when I minimise Nautilus or Firefox too. When this happens, compiz is also near the top of top. - I have tried using the default xorg graphics drivers and the proprietary nvidia ones, and the issue is the same. - My colleagues that have similar setups to me (same graphics card, 64bit, similar processors) don't have the same problem. However, I am the only one that has an encrypted home directory. So, to me this implies that the root cause is some incompatibility between an encrypted home and compiz/Unity, which Thunderbird also happens to be a victim of too. It may just be that Thunderbird tries to write more configuration/database stuff to the (encrypted) home directory when it is minimised than Nautilus or Firefox and so it's a lot more noticeable for Thunderbird than for the others. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/927515 Title: Thunderbird stuck at 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/927515/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
