           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

FilterImage::imageBufferFromPixelBuffer() makes an accelerated buffer, but doesn't use a RenderingPurpose option, so can trigger accelerated rendering in the web process. This will break when IOKit blocking is enabled.
