Comment #2 by Bruce STEERS:

I found if i make the picture Transparent

Dim p As Picture = New Picture(Obj.W, Obj.H, True)

then no bugs

or if not transparent I can fill the bg first with 

Dim p As Picture = New Picture(Obj.W, Obj.H, True)
p.Fill(Color.ButtonBackground)

So I guess gb.qt5 just does not initialize a non transparent picture cleanly like gtk3 does.
