REVISION SUMMARY
  On Wayland it can happen that a window is still in the stacking order
  although it is not visible. This is mostly the case for Plasma windows.
  So far the slideback effect did not ignore those windows and as they are
  higher in the stacking order than most other windows it blocked the
  effect from working once a Plasma panel element got closed.
  
  This change considers a window which has painting disabled in the
  stacking order as not usable and thus filters out all those windows.
