WebRender Planning

Here is a highlevel breakdown of the WebRender roadmap for 2019: https://github.com/orgs/FirefoxGraphics/projects/1
This document is a more detailed view of that roadmap, including burnup charts.

Q3 Priorities for WR

The priorities for Q3 (July/August/September) 2019

Correctness

General correctness bugs are currently tracked the following queries. These are not considered blockers for releases and will be re-triaged to assess importance on a regular basis:

• P3 68: https://mzl.la/2Yz2aKt
• WR-69: https://bugzilla.mozilla.org/show_bug.cgi?id=wr-69
• WR-70: https://bugzilla.mozilla.org/show_bug.cgi?id=wr-70

Continued roll-out of WR

One of our main objectives throughout 2019 is to bring WebRender to market on core platforms. For Q3, our main deliverables (in addition to the Android work referenced above) are:

• Identify target for initial WebRender release on Android
• Identify further Android releases/devices to target

WebRender on Desktop

• Ship WebRender to more platforms each release for the remainder of 2019
• Intel Windows 10 with low-res (less than 4K) screens - ride the trains for 69
  • Update (08/19) we are moving this target to 70 due to this issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1556634

Other

• V1 plan for non-WebRender code path options
• Determine how to measure battery impact of WebRender

The work documented there will help with these specific goals for Q3, as well as our plans throughout the year.
