Alice0775, I keep being impressed by the quality of your bug reports!
Alice, does this work now? I can't reproduce any problems on Nightly.

I can still reproduce the problem on Nightly47.0a1 with disabled e10s. https://hg.mozilla.org/mozilla-central/rev/0ecd7d72f232304da046b352c457e039e35ceed7 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0 ID:20160128030208
Recent regression, tracking.
Is this specific to Windows? It works with and without acceleration on OSX. It looks like it could be invalidation related, so it might have been fixed.
Fixed range: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=374e6d0abf0ebc19e84376181276f5cc53a6914a&tochange=5166d24e83a5aa6b0e7909d0e2e5c072a96732a8 So, this is fixed by Bug 1224433
Great, thanks Alice!
