No idea why you want to manipulate the resize flag, try just:

diff --git a/src/gui/kernel/qwidget_mac.mm b/src/gui/kernel/qwidget_mac.mm
index f58a755..d6a2741 100644
--- a/src/gui/kernel/qwidget_mac.mm
+++ b/src/gui/kernel/qwidget_mac.mm
@@ -4619,7 +4619,7 @@ void QWidgetPrivate::setGeometry_sys_helper(int x, int y, int w, int h, bool isM
 
         setWSGeometry(false, oldRect);
 
-        if (isResize && QApplicationPrivate::graphicsSystem())
+        if (isResize && QApplicationPrivate::graphicsSystem() && q->parentWidget())
             invalidateBuffer_resizeHelper(oldp, olds);
     }
