Excessive redraw causing flickering when viewing messages

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1659.2 Safari/537.36

Steps to reproduce:

After updating to the latest Daily build from 2013-10-07, and subsequent updates, I'm seeing excessive flickering when viewing messages. 

Just changing focus to/from TB you can see the flickering. 

This is on MacOS 10.7 (Lion), no other application is exhibiting this behaviour.

FYI, still see this on latest nightly of 2013-10-09:

Name 	Thunderbird
Version 	27.0a1
User Agent 	Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:27.0) Gecko/20100101 Thunderbird/27.0a1
Application Build ID 	20131009030201

Actual results:

Just viewing messages is enough to give you a headache.

You can see the flickering even when the message pane is empty, with no message displayed. 

It looks like the message pane is split in two, with most of the flickering on the right side.

Expected results:

Shouldn't be seeing this kind of flickering.
Yep, definitely an issue. Would be helpful to get a regression range though.
Ever confirmed: true
When you say regression range, what do you mean - do you mean between when I didn't see it and when I did?

Is there a way to see the update history? 

Doing a grep '^.*mozilla\.daily.*Thunderbird.*2013\(09\|10\)' on the system.log files would appear to give me:

So I believe that this points at me doing an update from 20130929 to 20131007. 

Unfortunately I can't seem to narrow it down any more than that.
That's exactly what I meant. :) And what you have is pretty helpful actually. But for even narrower results, I suggest to get a better regression range.

Just remember the --app=thunderbird argument. Though I see the issue too, so if you don't get a chance to do this today, I will later.
