All kinds of flickering on Mac
This is with todays nightly and layers-free. It seems to be a recent regression.
I'll try to narrow down what broke it.
I can confirm I was seeing this in my local build; I just assumed I had broken something.
I can confirm that this worked before the update to webrender 81cba6b139c4c1061cab6a1c38acf2ae7f50445d
And can confirm that it was that update that caused the flickering.
Binary search says: https://github.com/servo/webrender/pull/1635 is the culprit.
It seems like https://github.com/servo/webrender/pull/1635 may have just changed the symptoms. https://github.com/servo/webrender/pull/1625 broke shadow rendering for me on Mac.
i.e. this renders without a shadow. (After the a8 change it renders with a solid black shadow) --- root: items: - type: stacking-context bounds: [0, 0, 600, 600] items: - type: box-shadow bounds: [ 40, 40, 400, 400 ] blur-radius: 12 color: black
Priority: -- → P3
Very recent, just re-enabled webrender to check https://bugzilla.mozilla.org/show_bug.cgi?id=1391689 is fixed and noticed this issue. Was not present earlier.
We fixed this in https://github.com/servo/webrender/pull/1666, which has landed on central. I don't see it in the very latest nightly.

Still happening for me on 57.0a1 (2017-09-09) (64-bit), though not quite as much, but basically whenever the screen updates, such as when scrolling or typing.
