[Jonathan Kew [:jfkthame]]

Looks like this is a result of bug 594774; loading http://www.punypng.com/ in a debug build triggers the warning added there:

WARNING: Detected DOM modification during paint, bailing out!: file c:/mozdev/mozilla-central/layout/base/FrameLayerBuilder.cpp, line 1703

and the expected result is that painting will be incomplete (see comment at http://hg.mozilla.org/mozilla-central/rev/3c4af3fe446c#l1.63).

Immediately prior to this warning, there were a couple of assertions indicating that all is not well:

###!!! ASSERTION: Invalid window handle: 'Error', file c:/mozdev/mozilla-central/widget/src/windows/nsWindow.cpp, line 932
###!!! ASSERTION: Want to fire mutation events, but it's not safe: '(aNode->IsNodeOfType(nsINode::eCONTENT) && static_cast<nsIContent*>(aNode)-> IsInNativeAnonymousSubtree()) || sScriptBlockerCount == sRemovableScriptBlockerCount', file c:/mozdev/mozilla-central/content/base/src/nsContentUtils.cpp, line 3660
