### Is there an existing issue for this?

- [x] I have searched the [issue tracker](https://www.github.com/Kong/insomnia/issues) for this problem.

### Which sync method do you use?

- [ ] Insomnia Cloud sync.
- [ ] Local only

### Additional Information

I'm using Fedora 43 Workstation, which by default uses Gnome 49, a version that no longer supports X11 and only runs via Wayland. I noticed that Insomnia, in its version 12, now runs natively on Wayland and no longer via XWayland, and unfortunately, when doing this, the application's Title Bar doesn't work properly. I also can't make the application fullscreen because resizing it isn't working correctly.

Reproduce the issue with Insomnia 12 on Fedora 43/GNOME 49 under native Wayland, following the listed title-bar and fullscreen steps. Then trace the desktop window handling and fullscreen behavior; done means the title bar renders and responds smoothly, resizing works, and fullscreen can be entered.
