I'm seeing graphics corruption turn up in several page after updating to today's nightly.

The corruption occurs at the edge of the window when scrolling and stays until the page repaints so I bet it has to do with layer rotation.

I first saw this bug when visiting a google docs with comment, see screenshot for example.

i also see graphical corruption on latest nightly (osx), staying until a repaint.

Unchecking "Use hardware acceleration when available" works around the problem for me (Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:12.0a1) Gecko/20120129 Firefox/12.0a1)

Is this only happening to people on 10.7? I can't reproduce on 10.6. :(

If I could reproduce I could bisect.

I'm also on 10.7 running on the Discrete GPU.

It happens to me on 10.6, on TechCrunch.
It was much worse on a local debug build.

I can reproduce this on 10.6, but only with integrated graphics.

I'm also getting it on the same build on 10.7.2.  This is on a Mac Pro with a Radeon HD 4870.  I get it when scrolling rapidly through a page of images (A facebook photo gallery is a good example).  I also get corruption in the tab bar.

summary:     Bug 721467 - Add an optional codepath (currently enabled only for Adreno 200 GPUs) to only use glTexImage2D for texture uploads as glTexSubImage2D can be slow and/or buggy r=joe,BenWa

Currently running a build to make sure that backing it out fixes this bug.

FWIW, I can reproduce it scrolling through this bug, on 10.6.

i can reproduce it too by scrolling the page on 10.6 and 10.7 and its fix by disabling hardware accelerator from settings
