1592016 - Enable gfx.webrender.compositor by default on macOS

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, enhancement, P3)

Description

[Markus Stange [:mstange]]

Bug 1591523 will land a first implementation of the WebRender OS compositor but it'll still be off by default.

This bug tracks the issues that need to be fixed in order to turn it on by default.

Comment 1

[Markus Stange [:mstange]]

To clarify: WebRender will still be off by default on macOS once this lands. The goal in this bug is just to enable more efficient WebRender for people who have turned on WebRender manually.

Bug 1592739 is being backed out for causing regressions, so this needs to be disabled as well.

Please re-nominate when the status of this bug changes.

This causes test_menulist_position.xhtml to fail pretty consistently with "Labels vertically aligned for index 6" in M-1proc(c1). Not sure why, I'll look into it. It could be a fluke.

Comment 14

[Markus Stange [:mstange]]

Nevermind, that failure is from bug 1624599.
