Kitty Does Not Fill Screen After Switching Windows in Full-Screen Mode

[ryywh45]

Describe the bug When Kitty is in full-screen mode and I switch to another window and then switch back, Kitty remains in full-screen mode but does not fill the entire screen.

To Reproduce Steps to reproduce the behavior:

1. Open Kitty terminal.
2. Enter full-screen mode (top bar).
3. Switch to another window (e.g., using Alt+Tab or clicking on another window).
4. Switch back to the Kitty terminal window.
5. See the error: Kitty remains in full-screen mode but does not fill the entire screen.

This will be a bug in GNOME, you appear to be using an old version of GNOME. I cannot replicate using GNOME 46.1. Update and you should be fine.
