In case that goes at my address: Yes, it's the latest stellarsolver (and kstars) for sure. I build RPM packages and install them, so no chance it's grabbing a wrong version somewhere. For the other question I don't know the answer, I had relied on the post by Rafa that EKOS would debayer and send the RGB cube. But I have no way to confirm that.
Also, no limited resources active, AFAICT.

Storing focus images for separate analysis failed - I checked the option in the settings, but there's no files saved anywhere :(
