+++ This bug was initially created as a clone of Bug #1009980 +++ This bug is created based on Bug 1009980 Comment 8. *STR  Download the app 'Poppit' from the marketplace.  Launch 'Poppit'.  Start to play game *Actual result The poppit app is too slow to play. This problem happen only on master. I confirmed this by using master hamachi, master flame. The problem did not happen v1.4 flame.
I wonder if this is similar to 999841.
Blocking as observed in the video that the lag was very obvious and this is a regression in 2.0 Hoping the regression-window will help us find the root cause.

The following are two profilers of guimark2 on b2g master and 1.4 local build. b2g master spends more time on SurfaceStream_TripleBuffer::SwapProducer which invokes SharedSurfaceGralloc::Fence to read pixels. profiler on b2g master http://people.mozilla.org/~bgirard/cleopatra/#report=e05813461f2a43d6a67405543754f9065227327d profiler on b2g 1.4 http://people.mozilla.org/~bgirard/cleopatra/index.html?#report=676ff0707442bf07644d7a3ffe16457b2f295877
For what its worth, I saw a lot of SurfaceStream_TripleBuffer::SwapProducer recently in a game on win8 over in bug 1013039.
Triage: From comment 4, this looks like a regression. Waiting on a regression window before acting.

I just confirmed this issue was caused by below commit. changeset: 178703:a54345bfd338 user: Jonathan Watt <email@example.com> date: Tue Apr 15 19:02:23 2014 +0100 files: browser/components/shell/src/nsWindowsShellService.cpp content/svg/content/src/SVGFEImageElement.cpp gfx/2d/DataSurfaceHelpers.h image/public/imgIContainer.idl image/src/ClippedImage.cpp image description: Bug 950372 - Convert imgIContainer::GetFrame to return a Moz2D SourceSurface instead of a Thebes gfxASurface. r=mattwoodrow
Jonathan, I'd rather not just back this out if you have a chance to take a look and get us a "real" fix.

Peter, did bug 996929 not then fix this (in which case there must have been a later regression that regressed things again).
Flags: needinfo?(jwatt) → needinfo?(pchang)
It did not.
Taking this at the request of jwatt.

I looks like bug 996929 did the right thing to fix this, but the skia(-gl) backend code still wasn't doing the right thing.

Does this actually cause images to be cached in GPU? I had a similar patch, but I had to mark the surface as non-volatile for skia to do the right thing. Without that, I couldn't see any difference in the fishietank benchmark. static_cast<SourceSurfaceSkia*>(result.get())->mBitmap.setIsVolatile(false);
