            Bug ID: 196594
           Summary: [GTK][WPE] Use a timer to request the creation of
                    pending tiles
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: magomez at igalia.com
                CC: bugs-noreply at webkitgtk.org

During the first flush for a layer, CoordinatedGraphicsLayer::updateContentBuffers() renders the contents of the tiles required to cover the visible area. After that, it requests a new flush to render the required tiles that are not inside the visible area yet (but belong to the cover area). But this flush request is performed with a direct call to nofityFlushRequired(), and that's discarded because we are already on a layer flush, so the remaining tiles are not rendered unless a new layer flush happens because of some other component.
