Boards icons are glitched out on my screen

Hi,

For some reason, the boards icons for items, champions, etc are glitching out on me x_x Instead of seeing the individual icons I just get a jumbled up array of them, and sometimes I don't see anything at all.

Here's an image of what I mean (taken from a post on the Story, Art & Sound forum):

Any help would be appreciated :) I'm currently running on Safari version 10.0.3.

P.S. This is a repost from the Help & Support forum; Porocles asked me to see if I could get any assistance here.
