Further to my previous comment: * I'm currently running mozilla-thunderbird 1.5.0.4-0ubuntu6.06 with mozilla-thunderbird-enigmail 0.94-0ubuntu4.1 and no other Thunderbird extensions (at least no extensions reported in the list. I may have tried to install extensions in the past but there are none there now). I'm using a Gnome desktop (standard Ubuntu)
* I have tried using the free nvidia driver instead of the proprietary one -- no change * Creating a new user on my machine and running Thunderbird to see if the problem exists for them (config problem?) -- no change * The behaviour does not change depending on the quantity of messages in the folder being viewed (I have folders containing between 5 and 4000 items). * I primarily use a single IMAP account but I copied 200 messages to my local inbox and scrolling in this list does not change the behaviour. * Continually scrolling up and down does work the CPU very hard (but not in the message list or other applications) Hope that helps - Andrew -- message list slow scrolling https://launchpad.net/bugs/38054 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
