Does this happen in nightly only? Which phones?

It is looking like we may get the hahlo ua work we need for compatibility. Adding to list of tracking bugs.

Maple somewhat has this with a grey screen.  You have to scroll really fast in order to see this.  Nightly is more noticible without having to force it at all.

I got this to occur on the paulrouget.com/mwc-demos/nightly.html page as well with the MWC nightly build.

I am uncertain why this is assigned to me.  Reseting assignment and cc'ing Patrick.  I don't think I'm qualified to fix this bug.

No longer blocks MWC demo.  We should retest this site though.

Bug 746016 replaced checkerboarding. With the new behavior I am not able to reproduce the issue anymore neither in the demo or on the website. I am however seeing Bug 749568 when using the demo.

Tested on:
Nightly/15.0a1 2012-05-01
Device: HTC Desire/Motorola Droid Pro
OS: Android 2.2/Android 2.3.4
