Draw line on play gets distorted

Hi everyone,

Here is the problem, check the screenshots: and So this happens after I enter the play mode. What is it all about? I have made a custom spline editor for path finding, everything works well except this visual issue. Everything is drawn in the OnDrawGizmos().

Here is a piece of code I use to draw all the elements:

 for (int i = 0; i < BezierCoordinates.Length; i++)
     {
         t = i * fraction;
 
         p0pos = Point0.Position;
         p1pos = Point1.Position;
         p2pos = Point2.Position;
         pointCoords = ((1 - t) * (1 - t)) * p0pos + 2 * (1 - t) * t * p1pos + t * t * p2pos;
 
         BezierCoordinates[i] = pointCoords;
 
         if (i != BezierCoordinates.Length - 1)
         {
             Gizmos.color = PathLineColor;
             Gizmos.DrawLine(BezierCoordinates[i], BezierCoordinates[i + 1]);
         }
 
         if(drawSteps)
         {
             Gizmos.color = PathPointsColor;
             Gizmos.DrawWireSphere(BezierCoordinates[i], PathPointsSize);
         }
 
         Gizmos.color = PathLineColor;
         Gizmos.DrawLine(BezierCoordinates[BezierCoordinates.Length - 1], p2pos);
    }

Any suggestions? Hope to hear from someone! And thanks in advance.
