Problems with camera in reacTIVIsion

Hey everybody!

This is my first post. A month ago I got a pi 3b+ Raspberry to develop an interactive project using Reactivision and Processing. For this I got a Raspberry V2 camera module (the original). When I open the ReacTIVIvision window, this only opens partially (1/6) of the height, and total witdth. I’ve tried different ways to solve this, but I haven’t succeeded yet.

Please, could you give me some advice?
Thank you very much.
