How long does it freeze? I guess there's not a lot we can do about that since when the qml engine is working on creating the new window, it can't also update the main window at the same time

On the laptop with the specs above, the freeze is like ~2 seconds.
On my current pc there's also a freeze, but barely noticeable.

There isn't a lot we can really do about that other than general performance optimizations
