           Summary: REGRESSION(r272476) [GTK] Coordinated graphics crash
                    in DrawingAreaProxy and DrawingArea message loop
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

All these tests are consistently crashing with what seens to be a loop with DrawingAreaProxy::update() sending DrawingArea::didUpdate(), which sends back DrawingAreaProxy::Update() and so on.

PS: Did not bisect, but r272476 is the coord graphics commit in the range between r272473 (last good) and r272484 (first bad) directly related to this.
