having a problem with 5760x1080 and 6012x1080 resolutions. looks like here is where its taking a wrong turn.
public CactEyeCamera(Transform Position)
{
this.CameraTransform = Position;
CameraWidth = (int)(Screen.width*0.4f);
CameraHeight = (int)(Screen.height*0.4f);
which ends up giving a gui of like 2302x432. Tarsier works fine. they have a user config panel to where you choose what size the windows are.
