That is called screen tearing when you turn off Vsync (and is normal).
When Vertical sync is off, the graphicscard will not wait for the frame to be fully viewed on the display. So the graphicscard goes nuts and outputs ex. 120fps on a 60Hz LCD and does not wait for the display to fully view the previous frame. Thats why you see this
The solution is to activate vsync that capps your fps with monitor refresh rate. Ex. Monitor is 60Hz, you get Max 60fps. But another problem with vsync is that you can experience Input-lag with mouse and keyboard
