Confetti Infusion Visual bug?

[Titan.8215]

Hey there, I got a confetti infusion and its working fine on myself, but I asked two friends and even if they watched the effect, from time to time they told me that the effect was not showing up, specially when I ride my mount and go a bit far from them. Its weird because its only on them because I always see the effect and also its only confetti since I have aurilliim, chak, etc and all still working but confetti dont.

 

Its this a visual bug? I mean its ok because i dont have any bug but its not fun when you want to show it and some ppl dont see it.

 

The only thing which fixed it was re-equipping the infusion but its annoying to do it everytime it not show up.
