INDI Library v1.7.6 Released. (27 Feb 2019)
First release of 2019 comes with quite a few new drivers across the board along with significant performance improvements to INDI camera and live streaming performance. Many drivers received significant updates to improve performance & stability, while a few were re-written from scratch to be in line with INDI standards. Here are some of the highlights:

I’ve seen the Focuser system automatically select stars in the corners multiple times. This is certainly a poor choice if you have any off axis issues like tilt, or if you have coma in the corners that needs to be cropped out. It should try to pick stars within a center circle area of the image.
Secondly It can tend to grab rather large stars. If you’re imaging with an RC and you have diffraction spikes, this creates some issues on the focusing module knowing what is the best FWHM for that star. Alternatively I’ve seen it pick extremely small 1-2 pixel stars, then easily lose the star as the focusing routine starts. Seems the best option is to pick stars between an FWHM of 2-6 and anything outside of that size should be discarded. Of course, this might make things challenging if someone starts the focus routine out of focus. So maybe there are several steps where it picks any star first regardless of FWHM to try to get it in rough focus first, then it moves on to a star with an FWHM of 2-6 to ensure focus is accurate. This to me would be way more reliable.

I am glad that someone else has also noticed some unusual focusing behavior.
If I let the software select a star it always selects one near the upper left corner, fairly close to the edge. I would prefer that it selected one about a third of the way from the centre, if possible, to maximise the focus for the entire frame.
I think it is selecting one with an appropriate brightness so I am not be seing the second part of your issue.

I think having EKOS act more as a director of a symphony of tools (astrometry.net, PHD2, external autofocus, etc) would be better than locking up useful tools in the EKOS framework. This has been a real boon for the Windows/ASCOM world as there are tons of programs (ACP, Voyager, SGP, etc) that can be used to automate imaging and each one doesn't have to reinvent all the parts each time.

If you are attempting focus with Narrowband filters you need significantly longer exposures to have a star, which makes it worse.
