Issues with GDK Wayland (no correct positioning of the layout)

Hello,

I have checked already #67 and I already set `~/.config/hints/config.json` as following:
```
{
"backends": {
"atspi": {
"application_rules": {
"default": {
"scale_factor": 1.25
}
}
}
}
}
```

However my issue seems to be a bit different, it's not the scaling (I'm using 125% on ubuntu 24.04 atm). But the actual positioning of the layout.

I'm getting the following output running `hints -v`
```
(hints:38571): Gdk-CRITICAL **: 11:18:50.857: gdk_wayland_window_set_dbus_properties_libgtk_only: assertion 'GDK_IS_WAYLAND_WINDOW (window)' failed
Gdk-Message: 11:18:50.857: Window 0x11461120 is a temporary window without parent, application will not be able to position it on screen.
```

And I see as follow

And if I minimize as following:

So it seems to be a 2 thing issue, first that the positioning is not right, and inside that positioning, the buttons are not on the correct positions.

Than you, happy to give more context/log info if needed
