Incorrect sprite visuals

First question here so be gentle pls :)

My problem essentially is that a sprite while it looks correct in the scene view, it looks rather weird in game view. Does this have to do with something in Unity or my laptop is incapable of showing such thin lines.

My thoughts are that it is something in Unity, because when I scale-up the size of game view the sprite remains in the same state. However, when I change the size of the game view the sprite's outline flickers.

Unity version: 2018.2.7f1 Laptop: Lenovo edge 530

Here are some screenshots to illustrate my problem:
