Yep, it is a wayland issue. After updating gtk4 4.18.5, other gtk apps no longer have this issues. Not sure why this issue still exists in bottles.

You can try running the app with the environment variable:

I just have it setup globally in my system since gtk apps (specially libadwaita apps) outside of GNOME are just painful to use.
