1719688 - Add support for querying/setting webrender compositor in browserSettings

Status: RESOLVED FIXED

(WebExtensions :: General, enhancement, P3)

Description

[Mike Kaply [:mkaply]]

We need one more pref related to colormanagement (but actually webrender)

gfx.webrender.compositor

It's a boolean that enables the os compositor backends for webrender.

One suggestion was:

webRender.gfxWebrenderCompositor

but this seems redundant.

I'm wondering if I just keep this under colorManagement:

colorManagement.webRenderCompositor

Can you elaborate why we need this to be settable from extensions?

• This pref switch doesn't work at runtime (only on startup).
• WebRender compositor is not stable on some platforms or hardware.
