Comment 152 for bug 125970

I've discovered that the height of my browser window affects the scrolling performance, the shorter the window is the smoother the scrolling, the taller the window is the slower the scrolling.

I decided to try changing the height of my Firefox window by a few pixels at a time until the performance dropped to an unacceptable level (noticeable jerkiness), this ended up being roughly 820 pixels.
