TTT Crosshair grows when I shoot?

Whenever I shoot my crosshair grows, making it impossible for me to spray with any guns.

It used to be normal, as in static, but my GMod crashed and changed it to that, now i have no idea how to change it back.

I’ve asked around and none of my friends, or players on the same server have this isssue.

I tried checking multiple sites but can’t find anything.

Any idea how to turn it off?
