[bug] Application freezes when resized via a tauri command (Windows only)

[a5huynh]

Describe the bug

On Windows 11, when a window is resized via a tauri command, the window hangs and must be force quit via the task manager. On macOS / linux (Ubuntu 22.04).

A small repo with the error reproducible is available here: https://github.com/a5huynh/win-freeze

Reproduction

With a bare bones main.rs like so:

#![cfg_attr(
    all(not(debug_assertions), target_os = "windows"),
    windows_subsystem = "windows"
)]

use tauri::{LogicalSize, Size, Window};

fn main() {
    tauri::Builder::default()
        .invoke_handler(tauri::generate_handler![resize_window])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

#[tauri::command]
fn resize_window(window: Window, height: f64) {
    window
        .set_size(Size::Logical(LogicalSize {
            width: 800.0,
            height,
        }))
        .unwrap();
}

Calling resize_window from JS will cause the window to freeze.

Expected behavior

Window should be resized without freezing the window UI.

I'm investigating this. For now you can change your command to be async and it'll work.
