title: Unity Object bounces even before colliding with a boundary collider
body: <p>Im making a carrom kind of game where Im using physics for striker movement, the problem is my striker object bounces from the edge of the board even before there was a real collision between my striker object collider and the board edge colliders.
  Please check this video where I have highlighted my project setup, is I'm doing anything wrong here?</p>

  <p>I tried to fix it in many ways but wasn't able to reduce this offset and without resolving this issue I wasn't able to proceed further, because if there are 2 objects very near to each other and if the striker hits only one of those objects accurately still the nearest another object is also considering it as a collision even though there wasn't a real collision!</p>
  <p>Is this a known bug? if not how can I remove this offset and can have accurate collisions that are required for carrom kind of games (where multiple objects are near to other)?</p>
