1858361 - Call CanvasContext::SwapChainPresent() from ShareableCanvasRenderer::UpdateCompositableClient()

Status: RESOLVED FIXED

(Core :: Graphics: WebGPU, enhancement)

Description

[Sotaro Ikeda [:sotaro]]

CanvasContext::MaybeQueueSwapChainPresent() triggers to present swap chain by posting Runnable to current thread.
It could cause to skip to present CommandBuffer::Commit() rendering result multiple times. It depends on timing.

CommandBuffer::Commit() is called in Queue::Submit(). Then it seem better to present swap chain just after PWebGPUChild::SendQueueSubmit().

It seems better to call CanvasContext::SwapChainPresent() from ShareableCanvasRenderer::UpdateCompositableClient() like other canvases.
