            Bug ID: 256399
           Summary: [UI-side compositing] Guard against UI process hangs
                    caused by incorrect frame rate data
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Scrolling
          Assignee: webkit-unassigned at lists.webkit.org

There's some evidence of a UI-process (i.e. Safari) hang caused by RemoteLayerTreeEventDispatcher::waitForRenderingUpdateCompletionOrTimeout() taking too long. This could happen if m_stateCondition.waitUntil() has a long timeout, so impose a cap of 32ms on that timeout.
