[GAMEPLAY] Heimerdinger Turret "charge" meter not displaying correctly

I first reported this issue not too long ago in this thread, but I decided to re-make the thread because the title of the old thread was misleading. As you can see in the pictures, Heimerdinger's turrets are having their "charge meter" (the progress towards firing the beam attack) displaying a few pixels too high relative to the turret's health bar. I first noticed this bug on the Hexakill map, so I know it was occurring as of patch 5.10, but I don't know about before that. I later realized that this bug happens for Heimerdinger on ALL maps, not just Twisted Treeline. Also, it is visible to members of both teams. For comparison, here is a picture from a slightly older version of League showing what the Heimer turret display SHOULD look like: http://i.gyazo.com/604461e49f3175ee4946a090e3525652.png
