236484 2022-02-10 22:31:12 -0800 [GPU Process] RemoteImageBufferProxy should not sink itself to an Image or a NativeImage through its backend 2022-02-25 11:53:45 -0800 1 1 1 Unclassified WebKit Layout and Rendering WebKit Nightly Build Unspecified Unspecified RESOLVED FIXED InRadar P2 Normal --- 236508 236547 1 sabouhallawa sabouhallawa bfulgham jonlee simon.fraser webkit-bug-importer zalan oldest_to_newest 1840206 0 sabouhallawa 2022-02-10 22:31:12 -0800 After r289518, this bug has surfaced because now the intermediate ImageBuffers have to match the underlying ImageBuffer of the GraphicsContext. This means we create RemoteImageBufferProxy and we exercise the rendering through GPUProcess more often. The current implementation of sinkIntoNativeImage() and sinkIntoImage() has to go through the backend which is not right for RemoteImageBufferProxy. Accessing the IOSurface backend should only happen in GPUProcess. Otherwise we will hit this release assert: Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 WebKit 0x1d54e99a4 WTFCrashWithInfo(int, char const*, char const*, int) 1 WebKit 0x1d5b3940a
