Description: Hi I am not a developer, only a user. In 18.10 Cosmic with new Yaru theme: any application with long menus are overflowing and covering the menubar making impossible to slide mouse to the next menu. It affects long sub-menus too (this might be intended as it is same with other applications). It also affects Bionic Ubuntu with original ubuntu theme. When the menu is not wider than the available vertical area of the screen than they show up nicely aligned under the menu toolbar but when it is too large: it might even run edge to edge vertically. It happens when screen is too small or the window is too small. If you want: see pics from launchpad bug 1803706. Steps to Reproduce: 1.open any long menu, like format or edit on small screen; or size window small and open any menu that is longer than vertical length needed. 2. 3. Actual Results: Menu is covering menubar and other menus, even first submenu is usually higher and not aligned well. Expected Results: Menu should open under menubar and stay there. However if submenu is too long that can run edge to edge. That is true for other (not libreoffice) app too. However other apps open long menus nicely. Reproducible: Always User Profile Reset: No Additional Info: It affects others too as I have tried to report it to launchpad (bug 1803706) and another person sent similar pictures, affected Cosmic and Bionic both original Bionic and new Yaru theme.

This behavior is from GTK+ (so NOTOURBUG), but good luck trying to convince GNOME it’s a bug; they’re notoriously stubborn.
