Champion Glitches when Elderwood Bard's around

I played a few customs with friends as Elderwood Bard, one of the bots on the other team was a Kog'maw. Whenever the Kog'maw was in sight of me he glitched, kind of like how Udyr was with his massive crotch, and this streak of Kog just stretched across the map. I was the only one who could see this glitch, and don't really have photo proof right now.. Am I the only one seeing this? Or is it kinda just a random thing I'm making up? xD
