            Bug ID: 205387
           Summary: [CoordinatedGraphics] ThreadedDisplayRefreshMonitor is
                    never released
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: Gtk
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org

The problem is that DisplayRefreshMonitorManager::createMonitorForClient() always creates a new one for RenderingUpdateScheduler because it's not notified of the window screen change. So, createDisplayRefreshMonitor() is called every time, which returns a reference of the same object, but it's added to the monitors Vector of DisplayRefreshMonitorManager and never removed from there.
