[Wayland] top bar dynamic transparency flickers between transparent and solid when browing through menus

When browsing through the menu of a non-maximized window, the top bar flickers. It quickly changes between solid and translucent. I recorded this behaviour, you can find a screencast at https://people.debian.org/~biebl/gnome-shell-topbar.webm This problem is only reproducible under Wayland. I don't see it under Xorg. I could confirm the problem both in Debian sid (using GNOME 3.26.1) and Ubuntu 17.10.
