The flickering screen can be noticed on other devices like LG Optimus 2X (ULP GeForce) or Samsung Galaxy S2 (Mali-400MP). 

I'm not sure if there are any graphic issues or if the page is auto scrolling up and down for a couple of times (see attached screenshot).

The above screenshot looks like you simply pulled the page down with your finger. I'm more concerned about the first screenshot which I have seen on the Nexus One as well.

I've seen the first screenshot as well, also a lot in combination with bug 721383.
Could you perhaps test the testcase in that bug and report in that bug?

Yes, it looks like that. Here is a video while I was trying to reproduce this on Galaxy S2: http://youtu.be/vA8AjfzwvZ0

If a screenshot is taken, the result can be noticed in the 2nd screenshot attached.

I attached a new screenshot using the TC from bug 721383. I see a big yellow square and a little rectangle under it after the vkb is closed, but I cannot catch all of them in the screenshot, just small yellow areas.

In the above range I see bug 717283 which stands out.

Already tracked for Fennec, no need to track for all branches.

It could be some of the initialisation changes that went in with this could have caused this. Not sure if it's worth spending too much time on, as all this code will disappear soon, but if it's easily fixable I'll write a patch.

Received an Xperia Play this afternoon, (Adreno 205) and still see this; at least on Nightly. I have not tested Maple.

Comment 16

[Kevin Brosnan [Ex-Mozilla]]

This GPU is rather common, we need this sorted out for release.

Comment 17

[Aaron Train [:aaronmt]]

Tested Maple (tinderbox from 03/06), I still see this very frequently through normal operations of the browser.
