      When windows are repeatedly shown and hidden, xdg_surface_configure() may be called again before QWaylandXdgSurface::applyConfigure(). This causes 

      ASSERT: "m_pendingConfigureSerial != 0" in file qtwayland/src/plugins/shellintegration/xdg-shell/qwaylandxdgshell.cpp, line 351

       

      To reproduce: Run the example from QTBUG-87624 with the fix for that bug. Do this in a small compositor window so that the overlay window is always shown under the mouse. This will cause it to be repeatedly shown and hidden.
