            Bug ID: 186397
           Summary: Only display refresh monitors having requested display
                    refresh callback should get notified on screen
                    updates.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: pvollan at apple.com

Since all display refresh monitors in the WebContent process share a single UI process display link, we should make sure that only the monitors having requested callback, are getting notified on screen updates. This does not appear to be a problem currently, but we should safeguard the code for future code changes.
