Yup, sure. Same problem. Why can't you adopt my attempt to your problem?
Just replace the parent of the dock with a QMainWindow. Case closed.
The second best way is analysing the QMainWindow class and find out, what it
is doing special for docking widgets. I guess, they fiddle with the window
Your approach will suffer from being unpossible to save the dock states and
the like anyway, I *guess*.

If it's one, then it's in the highly obscure class of issues (pretty hard to
fully solvable in a multi platform toolkit).
