HI Res Bugging out on detailed drawings

Just caught this while doing a takeoff on a drawing that has a lot of points on it. The page kept freezing in place for about 4-5 seconds every time i tried panning or zooming. Turning off Hi Rez fixed the issue so its not that big of a deal. Just thought i would let the team there know. The picture below shows the area that was making the page freeze up. Its pretty obvious why.
