I've noticed on my mac, in a few programs (Safari/Preview) when I'm looking through a PDF that the scrolling speed sometimes changes.
I'm not sure what it is exactly. At first I thought It was how fast I scroll.
Sometimes it seems like its scrolling further while the page is already moving due to momentum.
I'm not sure what causes the fast scrolling is there anyone who knows what I'm talking about and knows how to control the scrolling speed (im not talking about the settings)
What exactly triggers the speed difference
