Alice, does this work now? I can't reproduce any problems on Nightly.

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
