Ah. That probably explains it: I run it on my N9. And while it scrolls, it just does so at a normal speed. No visual indicator either. Probably the rounded side of the screen that's playing up. I could be something else as well. I've seen graphical glitches in the Gallery view as well but less consistent. Time-stamps could solve that problem and allow you to store the results locally, even in a flat file if you like. Make the search done on a MPD server identifiable by timestamp and compare it to the time of the latest db update. The fetching itself seems pretty quick. But I have only tried it locally, so far.
