REVISION SUMMARY
  During login creating the connection to Wayland server may take longer
  than 1 second (KWin busy, high CPU and IO load, ...) causing
  WaylandConfig to time out and leave the backend in an inconsistent
  state.
  
  This patch increases the timeout to 3 seconds and sets the overall
  backend status to invalid. This will abort the pending KScreen operation
  and prevent it from interacting with the broken backend. The next
  KScreen operation will try to set up the backend again, hopefully
  successfuly this time.
  
  BUG: 416566
  FIXED-IN: 5.18.2

  R110 KScreen Library
