1869931 - WebGPU rendering is not synchronized to dom

Status: RESOLVED FIXED

(Core :: Graphics: WebGPU, defect)

Description

[Sotaro Ikeda [:sotaro]]

WebGPU rendering needs to be synchronized to dom like WebGL and canvas 2D. But the current rendering is not synchronized to dom.

[Sotaro Ikeda [:sotaro]]

If we want the synchronization of WebGPU, there are the followings

• [1] Use sync IPC with first rendering like WebGPU ClientWebGLContext::GetFrontBuffer()
• [2] Use wait for first rendering in RemoteTextureMap::GetRemoteTextureForDisplayList() that is going to be added by D194352 of Bug 1829026.
• [3] async wait at WebRenderAPI::HandleWrTransactionEvents() without sync IPC of [1]. It is going to be added at Bug 1863257.

[3] is ideal way to address the problem.

It seems better to apply [2] at first as short term solution. It could simplify RemoteTextureMap handling.
