The linear speed of the beam when drawing the vertical lines is MANY times (sometimes hundreds or thousands of times) faster (in mm/second of beam travel) than when drawing the horizontal tops and bottoms, which results in a difference in the nature of the display.

Unless it's extreme, which may be harmonics or other noise distortion. Florescent lighting is great for this by adding a nice thick top that sometimes dances or is haloed.
