            Bug ID: 228665
           Summary: [GPU Process]
                    RemoteRenderingBackend::releaseRemoteResource() should
                    not terminate the WebProcess if it cannot find the
                    resource in the cache
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas
          Assignee: webkit-unassigned at lists.webkit.org

If the WebProcess has sent a RemoteRenderingBackend.ReleaseRemoteResource message but the GPUProcess was terminated an has just been relaunched. The new relaunched GPUProcess will process this message for a resource which it has not recached it yet. In this scenario, the WebProcess will be mistakenly terminated.
