After some minor refactoring and experimenting I think I've found I way to make fetching historical messages so unobtrusive that you can scroll yourself away. The respective (very small) PR for libqmatrixclient is already submitted and hopefully will be merged soon; the Quaternion PR will follow shortly afterwards. |

…w much to fetch * getPreviousContent() won't be triggered during the model resetting; this should prevent unnecessary fetching reported in quotient-im#118. * Previously we used a hard 5-pixel margin to check if it's time to scroll and fetched strictly 10 messages. This led to stuttering when scrolling far back the timeline, as reported in quotient-im#94. The new code calculates whether there are enough pixels above to scroll at the same speed for the nearest 2 seconds, and if not, fetches additional messages that would amount to about 3 additional seconds of scrolling (assuming that an average height of a fetched message in pixels will be the same as the average message height for the already loaded timeline). Closes quotient-im#94, quotient-im#118

When scrolling upwards, more history get’s pulled in. But I can scroll so fast upwards, that I reach the upper end of log where no reload get’s triggered. I actually have to bounce the view against the top again and again everytime I want to pull more history.
