Display artifacts can be caused by software or hardware issues. First step is to reboot your Mac (easy fix for many software issues). If the problem persists, take a screenshot (Command-Shift-3) and if the issue on the display does not show up in the screenshot, the most likely cause is a hardware problem with the display (cable/panel/etc.). In that case, the next step is to contact Apple for service.
