Created attachment 8887504 [details] [diff] [review] Don't clear WebRenderPaintedBlobLayer From https://bugzilla.mozilla.org/show_bug.cgi?id=1379322#c2 Try WR looks good - https://treeherder.mozilla.org/#/jobs?repo=try&revision=a22d5aefc6ac43105c9380f80d540c3ec4f9fb81 Just hope WR is handling this correctly. ContentClient clears the buffer for us as needed to the right color, hence OMTP clearing it again was bad. WR needs something to clear the buffer to the right color as well then.
We initialize to opaque white. For this to be valid we need to switch this to transparent black: http://searchfox.org/mozilla-central/source/gfx/webrender_bindings/src/moz2d_renderer.rs#57
