Breeze Dark/Light dynamic switching

Hello.

Maybe anybody will know... In Plasma environment dynamic switching Breeze from 
Dark to Light and vice versa in my application changes everything correctly 
with exception of QMenuBar. It remains with old style till reopening of the 
application. But I'd like to have everything perfect... Interesting note - 
switching from Light to Dark remains QMenuBar in Light colors, switching back 
from Dark to Light makes QMenuBar dark. All menus (popups) change palette 
correctly, all perfect, the problem is only in the QMenuBar visual look.

Maybe anybody know how to workaround it?

Thank you.
