Apologies for the blatant self promotion :) You could try hermesgadget.and turn scrolling off.
This reader is an enhanced version (of Feed Headlines - which was no longer being updated) and is free, and is also used (by some) within MS.
At the risk of being distracting, I suggest you plug in your RSS feeds into the Google Reader and, start a Google Chrome session to view them.
It is quite minimalistic in a sense and very comfortable to navigate. You could use Rainmeter to setup a nice desktop with rss feeds.
We like free and open source stuff, but we'd appreciate if you could try to help out other people and not just advertise.
As I already mentioned, I'm using a Motorola Nexus 6 with stock Android 6.0.1 on it.
