How do I get these lines away in Minecraft Is not the Texture Pack?

I have such funny lines in Minecraft - they are only in the distance represented, near or in front of me I do not see such!

These are so-called artifacts. The result when a GPU is slowly at the end of their lifetime.

Or overclocked too much

Could of course be too. But I think less.

Do you mean this little green / red line?

If so, they indicate the x / y / z axes.

Have to press F3+ Q times. Will you then bottom left ne table listed with different F3+ keyboard shortcuts. One of them removes the.

Otherwise, do not see any lines.

If you mean the red / blue / green lines… They come automatically when you get the coordinates (press F3) and that's how they go!
