            Bug ID: 238846
           Summary: ImageBitmapRenderingContext::setOutputBitmap() can
                    trigger accelerated drawing in the webcontent process
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: simon.fraser at apple.com
                CC: dino at apple.com

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