Glenn Watson 6bfb59cac9 Bug 1708444 - Don't create compositor surfaces inside blend containers. r=gfx-reviewers,bradwerth If we optimize a root level blend container to be a tile cache, we need to ensure we don't promote compositor surfaces within this slice as it can result in incorrect blending.

wrench

wrench is a tool for debugging webrender outside of a browser engine.

Build

Build wrench with cargo build --release within the wrench directory.

headless

wrench has an optional headless mode for use in continuous integration. To run in headless mode, instead of using cargo run -- args, use ./headless.py args.

`show`

If you are working on gecko integration you can capture a frame via the following steps.

Visit about:support and check that the "Compositing" value in the "Graphics" table says "WebRender". Enable gfx.webrender.all in about:config if necessary to enable WebRender.
Hit ctrl-shift-3 to capture the frame. The data will be put in ~/wr-capture.
View the capture with wrench show ~/wr-capture.

`reftest`

Wrench also has a reftest system for catching regressions.

To run all reftests, run script/headless.py reftest
To run specific reftests, run script/headless.py reftest path/to/test/or/dir
To examine test failures, use the reftest analyzer
To add a new reftest, create an example frame and a reference frame in reftests/ and then add an entry to reftests/reftest.list
