  I don't think Qt allows this, the copy and move ctor should be deleted.
  
  There's another solution which might be cleaner and which KWin uses for that problem: modifying the process environment. I'll give a try whether this could work here.
  
  Btw it was a surprise to me that this unsetting is needed at all.
