To anyone affected by this problem,
We are sorry that we do not always have the capacity to review all
reported bugs in a timely manner. This bug was reported some time ago
and there have been many changes in Ubuntu and Thunderbird since that
time.
The upstream bug was closed "RESOLVED INCOMPLETE" in 2015. Does anyone
still see a problem related to the one that was reported using currently
supported versions of Ubuntu and Thunderbird?
Please let us know if you do otherwise this bug report can be left to
expire in approximately 60 days time.
Thank you for helping make Ubuntu better.

Title:
message list slow scrolling
Status in Mozilla Thunderbird:

Status in thunderbird package in Ubuntu:
Incomplete
Bug description:
Hi!
I'm on kubuntu dapper and using thunderbird as mail program.
When scrolling the message list of a folder, I have redraw rates of about 5
to 10 redraws per second. In other words: The list scrolls very slow and is
very unresponsive.
CPU goes up to 100% while scrolling.
I tested this with a empty profile just filled with about 100 mails in
the local inbox. No extensions, no themes, no IMAP connections, no
nothing.
I tested this with vanilla thunderbird downloaded from mozilla.org,
too and there the problem shows up, too. So it might be related to
something else I don't see yet.
I changed my GTK theme to default instead of gtk-qt. Looks ugly, but
problem still persists.
Interestingly when scrolling the message preview pane or an opened
message, scrolling is smooth, fast and very responsive. So graphic and
rendering subsystems cannot be involved into the source of the problem
I think.
Before testing dapper I used thunderbird on SuSE 9.1 and there were no
problems scrolling in message lists up to 20.000 mails. So it should
be able to do that fine on dapper, too. My hardware is absolutely
sufficient (Athlon XP 2800+, Geforce 6600 GT, nvidia closed source
driver configured correctly)
Any ideas?
Best,
Daniel
