           Summary: [GPU Process][FormControls] Create a NSView for
                    drawing controls parts only when it is needed
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org

For viewless drawing, we should not create the NSView. If we attempt to create an NSView while drawing a control part in GPU Process, that may throw an exception because creating an NSView or its NSWindow should happen only on the main thread.
