Please describe your issue in as much detail as possible:

Dynamic collections of a certain size (seem to be more than 30 games) makes it so that you can scroll way past the end of the collection.
This does not happen to static collections or even dynamic collections which had the issue that is snapshot to a static collection.

I'm not sure if this happens on other Distros as I'm not able to set up an environment for testing at this moment.

Steps for reproducing this issue:

1. Make sure you have a library of about 50+ games.
2. Create a Dynamic Collection
3. Set the snapshot filter to f.ex Single player (whichever filter yields the most results)
4. You can now scroll way past the end of the collection and the scrollbar barely moves.
