(Whiteboard: [gfx-noted])

I've reproduced on a nightly build (Mac OSX 10.10.5 with Intel Iris Pro 1536 MB) Follow the steps to reproduce here: https://people.mozilla.org/~sgiles/sandbox/imgels/flicker.html Not sure if this occurs on other platforms.
I can reproduce the flicker (on first button-press) on Linux Nightly, FWIW.

We might not fix this; in bug 1253995 we're changing nsImageFrame to use the stale image if it has the same intrinsic size, but in this particular test case the images are different sizes. Although it does make sense to do the same thing if width and height are fixed. Either way, this is either a WONTFIX or a dupe of bug 1253995.

fwiw, the observable effect wasn't fixed by https://bugzilla.mozilla.org/show_bug.cgi?id=1253995
