Incorrect command line arguments running three desktop application instances in a bat file

Dear All,
I need to run three application instances from a bat file. The problem is that different command line arguments (unity layer arguments) are not handled correctly. Here is an example of the bat file content.

START myunityapp.exe -screen-fullscreen 1 -screen-width 1920 -screen-height 1080
START myunityapp.exe -screen-fullscreen 0 -screen-width 1280 -screen-height 720
START myunityapp.exe -screen-fullscreen 0 -screen-width 1280 -screen-height 720

The problem is that sometimes it works fine but sometimes two instances are fullscreen, sometimes all instances are fullscreen.

Any idea?

Regards,
Gianni

 

I'd handle this in your opening scene rather than using these command line options.

https://docs.unity3d.com/2017.3/Documentation/ScriptReference/Screen-fullScreen.html

 

So, Unity guys must know that -screen-fullscreen command line option does not work?

 

If you've filed the bug they would know.

 

maybe not exactly related but
i noticed that the old way of running fullscreen/borderless window from command line didnt seem to work..(didnt investigate further if its some different player settings perhaps)

but pressing ctrl+enter on that windowed screen makes it fullscreen. (and next time it defaults to full screen)
