Description

DMS appears to be reloading Ghostty configuration on wallpaper switch, even with Ghostty toggled off under DMS Settings -> Theme & Colors -> Mutagen Templates.

To note: my Ghostty is installed from nixpkgs and its config is managed by home-manager on NixOS.

With my wallpapers set to cycle, I get a Ghostty toast notification that the configuration has been reloaded every time the wallpaper changes.

Expected Behavior

No configuration reload.

Steps to Reproduce & Installation Method

Install Ghostty from nixpkgs.
Configure Ghostty with home-manager.
Toggle off Ghostty in DMS Mutagen themes
Set wallpaper to cycle
