The menubar (and most context menus, and those message dialogs that have 
been welded, see tdf#130857) are native Qt menus, while 
QtGraphics_Controls::drawNativeControl is custom drawing of controls to 
make them look like native Qt ones.

As an idea: I'd expect that setting a corresponding application style 
should make the menu use the custom colors as well.

Using e.g. `QApplication::setStyle(QStyleFactory::create("Adwaita"));` 
causes the application (including the menu bar) to use that style, and 
it could potentially also make additional changes in 
QtGraphics_Controls::drawNativeControl unnecessary. (Maybe 
QApplication::setStyleSheet could also work instead if using a style 
sheet instead of a custom style.)
