I don't know. I'm currently using kubuntu 17.10 and a windows 7 virtual 
machine, but I've seen it with windows xp and my previous linux 
distributions (older versions of kubuntu, mageia, mandriva).
In any case, I'm not sure the cause it's the same both on windows and 
linux: in linux it's enough to drop a label on a form, and when I move 
it the position of the ghost selector diverges from the real one

under windows I need a more complex form and the ghost selector moves in 
sync with the real one.
Notice also how the ghost selector of the string grid is just one point.
