This a subset of bug 989858, and is blocking jwatt's conversion of imgIContainer::GetFrame.
Assignee: nobody → matt.woodrow
I guess this isn't ideal, but it's a lot easier than converting all of BasicLayers and lets us unblock jwatt's work. This can go away again once all the things are done.
Attachment #8403684 - Flags: review?(roc)
We're already requiring Moz2D backed gfxContexts for BasicLayers. This just avoids converting our Moz2D surface into a thebes one and then back again.

And this removes the last user of the 'deprecated' surfaces on Image, which makes the world a happier place.

Add gfxContext API to avoid converting between moz2d and thebes needlessly

After installing this patch on inbound I get massive graphic corruption when I scroll.  I did a regression test and narrowed it down to this patch.

I'm running Windows 8.1.1.

Turning off HWA produces no corruption.

FYI... Left HWA enabled and turned off OMTC and there is no corruption.

Any confirmation of my findings?
Are you sure it's this bug? I strongly suspect you're seeing something related to Bug 992486 (which landed at the same time).
I could only find this patch when I did my regression testing using the inbounds.  I can't find the files that contain 992486.  Is there a separate file that contains 992486 and not 993784?
No there isn't, sorry. I can have a look locally I guess.
If the file I used on inbound contains both patches then it's a toss up as to which one is causing my problem. I'm just trying to prevent a bad patch from hitting Nightly.
I reproduced this locally, it is indeed bug 992486. I'll fix it.
