Thank you for contacting us.
There should be no difference in the layout of your forms if the screen resolution of both systems is the same. Even if one of the systems has a lower resolution, this should only reduce the available screen space and should not disrupt the layout of the controls on your form.
Can you please provide us with some additional details: system localization and screen DPI settings of both operating system, as well as some screenshots which demonstrate the look of the forms on each system? This will let us provide you with proper answer.
I am looking forward to hearing from you.
