Can confirm this doesn't work on Debian KDE desktop environment

[leaanthony]

Have you used git bisect to determine if it ever worked in KDE?

[zveinn]

I did not, but I just figured I´d add it to the comment since the original author is using zorin OS which only support GNOME and XFACE according to it´s documentation

[lyimmi]

I can confirm that the resize disabling is not working on Ubuntu 23.04 gnome either.

I went back to the 2.0.0 release and its broken there too, I think its not a Wails problem. 😕 I'm trying to figure it out.

[lyimmi]

I found the problem. In the NewWindow function we set the window's initial size with gtk_window_resize, if I set the initial size with gtk_window_set_default_size everything works as expected.

I'll make a PR for this.

edit: I clearly remember this working. I don't know, maybe GTK changed something?

[lyimmi]

@ramy100, @zveinn I made a PR could you please test it?
