My crosshair faded?

At fortnite, my crosshair on the sniper fades why? So it's not gone but not really there either, it's more blurry but why? Two days ago everything was fine and I didn't do anything in the settings.

With my buddy this is normal and in csgo it is at least still visible here I can only see it blurry

I have the problem on PC but it got better as the game progressed

Not with me yet
