I do see a little bit of flicker in this test case. We should take a look at this.

Tracking for 49, if anyone fixes this please request uplift so we get it into 48 too.
Just circling back on this bug - we're tracking for 49 but right now no assignee - Jim do you plan to own this bug? Thanks.

No it's currently an e10s tracking + P3 so non-blocking, lower priority.

Hi Jim,
May I know is there any plan to fix this in 49?

No there is not. This is polish work tied to e10s, currently a p3.
Also I can't reproduce, are people still seeing this?

Yes, on Win 7 x64 with the latest Nightly, it's still visible.

Hmm, that's what I'm testing on and I don't see a flicker issue. I wonder if this is tied to graphic cards in some way.
