i am trying to understand where the problem is.. can you help ?

Hm, at first glance I can't see what might be causing this.

1. Which of the scripts are you using? Active, focused or primary?
2. Which version?
3. By "first/second monitor" you mean primary/secondary?
4. Do you have any other KWin scripts enabled?
5. Do you have any window rules targeting screen or position?
6. Can you please post the output of qdbus org.kde.KWin /KWin supportInformation, section Screens?
7. BTW, may I ask what you used to get that display information?

I noticed this happens with XWayland windows which attempt to force remember their positions. This is the case for mGBA and CafeTran Espresso (my main work tool) for instance.

A possible workaround is to create a window rule with the property Ignore requested geometry set to Force: Yes. This can cause issues with dialogs also following the default window placement (e.g. Maximized), but then one can disable the dialog window type.

@herzenschein This is a plausible hypothesis and a good idea for a workaround; thank you.

@koloved, are all windows placed on the wrong screen, or only some applications?
