Hello,
I was trying some indoor tests with Pi3 and Ubuntu Mate. before starting I did the update of both Mate and indi. My configuration is:
Mount EqMod (used simulator for indoor test)
CCD Moravian G2-8300
Guide camera: QHY5-II M
I basically tested CCD managing and what I found is memory problem in FITS preview as is reported in the log file:

2016-08-17T17:26:35.115 - WARN - QImage: out of memory, returning null
This happens in capturing if I play with the fit (zoom, autostretch etc) and in focus: in this case is quite impossible to do anything but unpower the Pi3.
In case of crashes, if I run KStars again, Ekos complains about another server is running and asks me whether I want to shut it down. Anyway it can't do it maybe because indi-mi driver is busy or blocked, in fact I can't use the CCD, I have to kill the process by command line.
I know Pi3 has only 1GB of ram but during the normal usage KStars uses less the 50% thanks to the last Jansem commits. I wonder whether FITS viewer could also be optimized, in focusing framing above all.
Last note: windows are not re-sizable so it's very difficult to work with them and sometimes you can't see important footer buttons, maybe a new interface is under developing?
Thanks in advance for your support, I'm available for every test to be performed on Pi3.
Clear Skies,
Giovanni.
