Mouse position at a different point than crosshair cursor

How do I change my cursor/mouse settings such that there isn't an unnecessary offset which makes drawing anything extremely difficult? When I click to draw where I want my line to be, the actual line drawn appears at a distance away. Even when selecting entities I have to hover at the blank space to find my drawn line instead of clicking directly on the line due to some invisible offset. I have tried playing around with the different options but haven't seem to find the right one. I'd appreciate any help! Thank you very much!
