<b>Note:</b> WebRender may still be disabled by other runtime conditions. Common conditions include a disabled GPU process (on Windows) or disabled hardware acceleration. You can check the WebRender status by going to about:support and looking at the WebRender line in the graphics section. On Linux hardware acceleration is disabled by default, so set <tt>layers.acceleration.force-enabled</tt> to true in about:config (restart required), or run with <tt>MOZ_ACCELERATED=1</tt> in the environment to ensure HWA is enabled and doesn't block WebRender. | <b>Note:</b> WebRender may still be disabled by other runtime conditions.

You can hack on WebRender either via a checkout of mozilla-central or via a checkout of the webrender repository. Using mozilla-central allows you to easily build/test Firefox and trigger try pushes, especially when you have interdependent changes across Firefox and WebRender. You can also build standalone WebRender from within mozilla-central, via i.e. | |||
cd gfx/webrender | |||
cargo build --features=capture,replay,pathfinder | |||
If you use mozilla-central, you have the option to request review via Phabricator, but your final changes must not land directly, and should be submitted to the standalone WebRender repository. Git users can do this like so: | |||
cd /path/to/m-c | |||
git format-patch -pk --relative=gfx BASE_REVISION gfx/webrender gfx/webrender_api | |||
cd /path/to/webrender | |||
git checkout -b my_branch | |||
git am /path/to/m-c/0* | |||
git push my_branch | |||
You should then ping a bors operator to carry your apply your r+ to the GitHub PR. Once your change lands in upstream WebRender, it will be synced to mozilla-central within a day or two. | |||
