but this effect

window.set_decorations(false).unwrap(); 

[project-AI39]

I'm also facing the same issue where "decorations": false doesn't work, In my case, clearing the cache %APPDATA%/(your-app-identifier) folder resolved the problem. I'm not sure if it will work for your environment, but I hope this helps a little.

Since you seem to be also using window state plugin, maybe check if https://github.com/tauri-apps/plugins-workspace/issues/2203#issuecomment-2540412621 helps?

This might not be very intuitive, but window state plugin saves and restores the decoration state by default (it means if you used decorations: true the first time and decorations: false the second time, the decorations will be restored to true because it's saved in that way), you can disable it through with_state_flags though
