1492398 - Suppress CompositorBridgeParent::RecvAdoptChild()

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, enhancement, P3)

Description

[Sotaro Ikeda [:sotaro OOO July/27 - July/31]]

Suppress CompositorBridgeParent::RecvAdoptChild() when WebRenderBridgeParent is created by CrossProcessCompositorBridgeParent::AllocPWebRenderBridgeParent().

In current gecko, CompositorBridgeParent::RecvAdoptChild() was always called just after WebRenderBridgeParent creation. It is not good.

RecvAdoptChild() is triggered by RenderFrameParent::AttachLayerManager(). The AttachLayerManager() is called by nsFrameLoader::ShowRemoteFrame() and RenderFrameParent::OwnerContentChanged(). The ShowRemoteFrame() is always called when Tab is created.
