Accidental fast scrolling in Android

I have an Android 2.2.1 device, and I keep noticing what may be a glitch in the scrolling. This happens in all applications in which scrolling occurs, but most frequently in Twitter. I’ll be slowly scrolling along, swipe… swipe… swipe… trying to catch up with dozens of tweets, when all of a sudden the scrolling takes off lightning fast.

When it takes off, it goes much faster than I’m ever able to make it go, which leaves me with the impression that I’m invoking a feature. But I can’t purposefully recreate this accidental fast scrolling. The closest I could come was when I lifted my finger at the end of the swipe, and my finger was near the top of the application. But I can’t swear that this is where my finger is each time it happens.

Others before me have wondered whether this is a bug or a feature.

The thing is, I’m not even trying to go fast, I’m actually doing slow, short swipes while trying to scan a screen’s worth of content at a time, so when it starts scrolling quickly, I have to mash my finger down to put on the brakes, then scroll back to wherever I was.

Update 08.27.11: Could the fast scrolling happen when I scroll at the same time extra data is being lazy-loaded by the browser or app? So, I scroll a little bit, and the page starts loading some images, and before it’s done rendering, I scroll again. The page then finishes loading the images and processes the scroll event, but due to some glitch, goes berserk.
