1646073 - Enable WebGL and WebXR SwapChain pooling on Android

Status: RESOLVED FIXED

(Core :: Graphics: CanvasWebGL, enhancement)

Description

[Imanol Fernandez]

After https://phabricator.services.mozilla.com/D78533 patch, WebGL/WebXR are instancing surfaces every frame instead of using a pool. This is causing a performance hit on Android due to long SurfaceTexture destructor times (profile: https://share.firefox.dev/2z49nu5)

We need to enable poolong just on Android.

Attachment: Bug 1646073 - Enable WebGL SwapChain pooling on Android. Use a separate SwapChain for WebVR.

• Enable WebGL SwapChain pooling on Android. Creating and releasing Android Surfaces every frame causes a big performance hit due to AndroidSurface slow destructors bug.
• Add a separate SwapChain for WebVR. We are already using separate SwapChains for WebXR (WebGLFramebuffer::mOpaqueSwapChain) but not for WebVR (it uses the canvas backbuffer).
