Maximizing Viewport changes game behavior

Ok so here's a weird one. When I run my game in the editor without the game viewport maximized it behaves as expected. Then when I maximize the viewport "OnTriggerStay2D" stops firing. The game can be running in play mode, working fine, then without stopping I can maximize the viewport and I stop getting those triggers.

The game window doesn't change size, it's 1334x750 either way, it just gets more padding around it when maximized.

It doesn't seem like maximizing the viewport should have any effect whatsoever on the running game but it clearly does. I have no clue how to even debug something like this.

 void OnTriggerStay2D(Collider2D other) {
         
     //Debug.Log (other.gameObject.name);
     //drawDebugRect (other.collider2D.bounds.min, other.collider2D.bounds.max);
 
     //If the drill trigger is in the block call reduce health
     if (other.gameObject.CompareTag("Drill") ) {

             //ADDED TO CHECK THIS BUG ONLY
         Debug.Log (Time.time);

         //OrientedBlock block = transform.parent.gameObject.GetComponent<OrientedBlock>();
         x = Mathf.FloorToInt(myTransform.localPosition.x);
         y = Mathf.FloorToInt(-myTransform.localPosition.y);    
             
         float damage = ((Drill)other.gameObject.GetComponent("Drill")).damagePerSecond * Time.deltaTime;
         health = levelManager.reduceBlockHealth (x,y,damage);
     }
 }

It the Debug.Log statment stops outputing to the console in maximized but outputs just fine when not maximized.
