Subject: [PATCH] khamburgermenu: Ensure menu is polished before creating
window
By force creating the window, there is no chance for the style
to change the surface format that will be used because it's fixed
once the window has been created.
This caused for example in a graphical glitch with Breeze, so
manually ensure the menu is polished.
