--- Comment #4 from Jan-Marek Glogowski <glogow at fbihome.de> ---
The Menubar is a native QMenu widget, while the popup menus aren't. Menu
drawing in VCL is conflicting with the way Qt draws menus, so there is a lot of
clipping and reversing the way VCL paints the menu with temporary images etc. I
guess this is the origin of the problem.

Solution: someone has to implement popup menus with native QMenus and I guess
this will solve the problem.
