Any drop-down menu will flicker on-screen for an instant but will not stay open.
If this is a known bug feel free to close; if this is an unknown bug, let me know and I will try to reproduce it.
Steps to Reproduce:
1. When logging into Manjaro, choose Wayland instead of X11. (you may need to install Wayland)
2. Open LibreOffice Writer
3. try to open a dropdown menu, such as the font selection dropdown, the font size dropdown, or the Set Line Spacing dropdown.
The menu will appear for a split second but will disappear instantly. You will not be able to interact with the menu because it disappears too fast.
The dropdown menu should stay open until the user chooses an option or clicks elsewhere on screen.
