REVISION SUMMARY
  On Wayland aurorae was creating a lot of stress for the system and
  basically turning the system unusable in a short time. This was due to
  a recursion starting to create OpenGL contexts. The window created a
  decoration (aurorae) which created a QQuickWindow. For that KWin creates
  an internal window which in turn triggers the creation of a window
  decoration and so on and on.
  
  By simply setting the render QQuickWindow as frameless we can prevent
  this recursion.

TEST PLAN
  Tested on Wayland and X11. On Wayland the recursion is gone.
