Hi..
The photo you are using is not best suited to FaceFilter as it isn't a front facing photo. The problem could be because of this or you may have a graphical issue due to your graphics drivers.
Please try the following:
1. Update your graphics drivers. You can check with Nvidia, AMD or Intel depending on the graphics card you are using.
2. Try using a fully front facing photo and see if the same issue occurs. You can easily find a suitable image to try out by searching on Google or Bing for face photos.
