With the Q2 release, we introduced several non-compatible changes to the endless scrolling behavior. The breaking changes in question have been documented in our changes and backwards compatibility section. The virtual mode implementation details and behavior have been documented in the listview getting started section. In addition to that, our live demos feature updated examples which showcase how the new approach works.
However, several of our customers have reported problems while migrating their previous implementations to the new approach. Most of the time, the problems were due to misconfigured datasource. The problems we have traced so far are:
- server paging was not enabled;
- page size set to a low number (please check the documentation above)
- server paging not working due to missing schema.total configuration
- complex templates with images which stretched the items after being loaded.
In your case the problem comes from the small page size that you have set. With the new implementation the bigger your screen is the more items you need in your page size.
