In various applications that we launch via Xwayland, pull down menus are broken. This is very painful in Calamares, the installer we want to use in the upcoming Ubuntu 26.04 Lomiri Remix. But the problem can also be observed with any GTK-3 application (such as gedit) when exporting GDK_BACKEND=x11 to the environment. So, ... to reproduce the problem: * install Lomiri (Debian unstable, Ubuntu 24.04 + Lomiri PPA, Ubuntu 26.05): `apt-get install lomiri` * install a GTK-3 app, such as gedit (or any other GTK-3 app with pull-down menus) * open a terminal (Terminal, from Lomiri's launcher) * `export GDK_BACKEND=x11` * `gedit` Then click on the hamburger menu, open Settings, switch to tab "Fonts and Colors". There is a pull-down menu "Theme variants": click on it, and nothing happens. Alternatively, start gedit from a shell without previously setting GDK_BACKEND=x11 and who will see a functional pull-down menu (rendered via Wayland instead of X11). Another test application can be obtained like this: `sudo apt install gtk-3-examples` and run `gtk-3-demo`. This issue is fixed once pull-down menus render the same way in X11 and Wayland.
