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? 538387 4 kbr 2012-01-18 18:24:33 -0800 See comment on Bug 76239. 546337 5 twiz 2012-01-31 12:02:55 -0800 Fixed by issue 76654. *** This bug has been marked as a duplicate of bug 76654 ***
