Steps to reproduce:

1. Get a gmail account and send it lots of emails including a few that are long
   enough to cause scrolling
2. Go to the gmail inbox.
3. Scroll the pane to the right which contains the list of all email threads
   listed by subject.
4. Click on a thread which contains email long enough to cause a scrollable view.
5. Scroll the email thread.
6. There is no step six.

Expected results:
In steps 3 and 5, only repaint the newly scrolled in areas.

Actual results:
The whole scrollable pane repaints.


There appears many other invalidation issues in this UI. I'll try to file separate bugs on those as needed.

This appears to be a dlbi regression since it was working fine in an older build.
WFM on trunk. Fixed?
I still see this, however only after having interacted with the page for a bit. See also bug 802385 comment 2 which seems very similar.

When the bugzilla page gets into this state it affects all scrollable areas on the page, so whatever "state" that's getting messed up seems to not be scrollable-region specific, but page-wide.
Enabling a persona seems to be required to trigger this. I can't trigger it with no persona enabled, but once enabled it happens almost immediately for me. I'm currently using this one:

I'm pretty sure this was fixed by bug 802385
