Here is a trace while copying emails between folders on an IMAP server. Some work is actually being done, but there seems to be a lot of time spent in
Paint::PresShell::Paint
nsLayoutUtils::PaintFrame
nsDisplayList::PaintRoot

Title:
  Thunderbird: high CPU usage from progress bars

Status in Mozilla Thunderbird Mail and News:
  Confirmed
Status in thunderbird package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: mozilla-thunderbird

  When sending a simple and short email with Thunderbird via SMTP the
  CPU is used intensively. This seems not to be necessary. If the
  sending failed and an corresponding error message dialog appears, the
  CPU is still being used. When pressing ok to close the error dialog
  the CPU is fine. This suggests it might be related specifically to the
  progress bar.  Such behavior is especially annoying on a laptop where
  you can hear the CPU usage because of a starting fan.
