Copy from #76239:
Sorry, I should notify that the fix for this might expose the failure for these kind of cases which don't occur before. This kind of failure is somewhat random. Actually both 2 cases are almost the same.
The reason could be see from here: http://code.google.com/p/chromium/issues/detail?id=104740#c5
This case is also to test DrawingBuffer. And the root cause of this case is the same. The failure is because of the V8 GC issue. 

There are 2 ways:
1) revert the patch and commit it together with the patch for #76225(release GL context).
2) Or don't revert it and it will get fixed with the patch for #76225.
what's your opinion?
