            Bug ID: 221673
           Summary: Page updates and rAF callbacks should run at a
                    frequency close to 60Hz on high refresh-rate displays
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org

Currently if you plug a 144Hz display into a Mac Mini, WebKit will update the page and fire rAF callbacks at 144Hz.

However, we should ensure that rAF, non-accelerated animations and page rendering in general refreshes at closest interval to the one used for 60Hz, so that we would run at 72Hz on a 144Hz display.
