[Gameplay/Client] Rek'sai tunnels graphical glitching

The glitch is that on Rek'sai's tunnels, specifically the entrances, that causes the outline of the model to flash brightly. I believe it is the lighting affect created by the model that flashes.

The conditions that caused the affect was for the player champion to be within one screen of a tunnel but did not seem to occur using the free camera. Another (friendly) player [Ashe] in the game confirmed that they had the same graphical glitch while the (friendly) Rek'sai did not see the glitch. I am unable to replicate this myself as I don't own Rek'sai.

I believe the glitch will be to do with either hardware issues or more likely due to the graphics settings within the game, as the Ashe and I both had our games on the preset high settings while the Rek'sai was on lower custom settings.

Would appreciate someone having a look at this, it wasn't particularly distracting but all the same to patch a glitch. Thank you.

N.B. The conditions that it occurred under where: Summoners Rift map, Rek'sai tunnels on purple side mid lane outer turret; Preset high in-game graphics settings
