After one of the recent patches there is some kind of rendering error of the speed effect of the Speed Pylon. This speed effect is displayed on my character after using the Speed Pylon. If my character is facing the camera at a certain angle range, there is some kind of doted cone behind my hero instead of the normal effect. This bug should be very easy to replicate, because it happens every single time when using the Speed Pylon.
