WebRender Q3 2020

The purpose of this document is to highlight our priorities for WebRender in Q3 (July/August/September) of 2020

We also have a high-level roadmap that outlines what we will work on and roughly when.

Where have we shipped WebRender?

For a list of the various places we have shipped WebRender, see:

Core Priorities

Shipping WebRender

We want to keep shipping WebRender to as many targets as possible each quarter.

Below is a list of releases in Q3 and what we are aiming to ship per release:


  • Win 10 - Intel - Gen 8 (Laptops and desktop, all screens)
  • Win 10 - Intel - Gen 7.5 (Desktop, all screens)


  • Win 10 - Intel - Loosen blocklist restriction v1


  • Win 10 - Loosen release blocklist
  • Win 10 - Gen 7.5 (Laptops)

As part of this effort, we will need to monitor and fix any critical correctness or perf bugs that appear that could potentially block shipping those targets or could impact users in release.

Unblock more Platforms

Our efforts to ship WebRender so far have largely focused on Windows. In H2 we want to start focusing on other platforms we would like to ship in 2020.

We will be working on burning down bugs that block WebRender from shipping on Mac

We will be working on burning down bugs that block WebRender from shipping on Linux

The goal for both Linux and Mac this quarter will be to determine when WR can ride to release on these platforms. This will be a combination of fixing correctness and perf related issues.

We keep track of key bugs we are working on here:

Software WebRender

We will continue working on SW-WR (or SWGL) throughout Q3 - specific monthly goals will be added as we proceed.
