Crosshair Error

Hi guys, i dont remember when it happened, but my crosshair goes wrong. His position is more on left, then he should be. Its not about recoil, i understand, what im writing. For exampl he become red if i navigate it lefter on ppl, then i did it earlier. I made screens, on them i just make one shot in the wall and didnt move my mouse. I play on 24" wide monitor.
