Title Bar Accidental resizes the window when moving and the game doesn't refresh

The game needs an option to disable the window from being accidently resized.   
I accidently tried to move the game window holding the title bar down but somehow it ended up stretching/pulling the window.

Also there are strips of black bars along the bottom of the game when this happens which means bounding boxes (hitboxes) are out of sync which creates other issues.

Can we get an option in the game settings to disable window from resizing after we've set the size we want.?
This prevents any accidental changes to the window size in middle of gameplay.
