(Linux) GTK Titlebar Reappears When Maximizing and Minimizing Ghostty Window to Normal regardless of the conf file

[dagimg-dot]

Even with gtk-titlebar = false set in the Ghostty configuration file, the title bar reappears when the Ghostty window is maximized and then minimized to normal window. This behavior persists despite the explicit setting to disable the title bar.

Environment:

• Operating System: Fedora 41
• Desktop Environment: GNOME 47.2

Ghostty Information:

• Version: 1.0.2-main+ff9414d9
• Build Channel: tip
• Build Config:
  • Zig Version: 0.13.0
  • Build Mode: ReleaseFast
  • App Runtime: GTK
  • Font Engine: Fontconfig + Freetype
  • Renderer: OpenGL
  • Libxev Backend: io_uring
  • Desktop Environment: GNOME
  • GTK Version:
    • Build: 4.16.5
    • Runtime: 4.16.5
  • Libadwaita: Enabled
    • Build: 1.6.2
    • Runtime: 1.6.2
  • LibX11: Enabled
  • Libwayland: Enabled

Steps to Reproduce:

1. Set gtk-titlebar = false in the Ghostty configuration file.
2. Launch Ghostty.
3. Maximize the Ghostty window.
4. Minimize the Ghostty window.
5. Observe that the title bar reappears even though it was initially disabled.

Expected Behavior:
The title bar should remain hidden at all times, regardless of window state (maximized, minimized, or normal).

Actual Behavior:
The title bar reappears after maximizing and then minimizing the Ghostty window, contrary to the configuration setting.

To add to the report.
Current way to "fix" this issue is to set gtk-adwaita = false

I have also set window-decoration = server and that results in following situation (without gtk-adwaita = false)

So basically, both SSD and CSD are active 😅

Same in hyprland. gtk-adwaita = false does appear to fix it, but then we do not have transparency anymore.

There is one quick fix for this. Ctrl+Shift+, reloads the config and removes the titlebar. In this screenshot, the lazygit terminal was fullscreened and then exited. It had titlebar back, but reloading the config like this on it fixed the problem.
