Click to lower windows does not work on Wayland
In Tweaks->Window Titlebars, there is an option to set a Titlebar Action of "Lower", i.e. you can lower a window when double/middle/secondary-clicking its titlebar. However, this feature does not work on Wayland for some programs, while it does work in Xorg sessions.
Despite this, the "Raise window if covered, otherwise lower it" keyboard shortcut does work for programs for which click-to-lower doesn't.
Programs for which click-to-lower doesn't work in Wayland:
- Calculator
- Evince (Flatpak)
- Evolution
- Files
- LibreOffice
- Settings
- Software
- Terminal
- Text Editor
- Tweaks
- Web
Ones where click-to-lower does work in Wayland:
- Firefox
- GIMP (Flatpak)
- TeXstudio
- gVim
- glxgears
