Facts I've noticed so far; * The reftest doesn't fail with WebRender on Android emulator. * The reftest doesn't fail on a single run, it fails on the second run on --run-until-failure runs * The reftest does fail on the second run on --run-until-failure runs even if specifying the same from and to animation value [here](https://searchfox.org/mozilla-central/rev/0e309417bdc73be33fc93f6bd7a0d4063d2c6e51/layout/reftests/bugs/1078262-1.html#27-289) The third fact is quite odd. I presume there is an underlying issue on the compositor side that bug 1078262 didn't solve, to be precise at that time the transform animation in the reftest were not able to run on the compositor, but with partial pre-rendering, it can be run on the compositor.
