Adding to this, it seems like there's a general scroll bug. It's better in Beta 5, as I can actually scroll back up now, but I notice my first scroll down with the scroll wheel almost feels like two ticks instead of one, with the next couple working ok, with another spike after, and repeat. Scrolling up never has these spikes and works as expected. The current view doesn't seem to make a difference (so I don't think it's number of games shown), as the same behavior happens with 50 games in a list, or 5000.
