Recent regression, tracking.

Comment 6

[Matt Woodrow (:mattwoodrow)]

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
