Did you do an update of kstars? I've seen that change some settings (like toolbar visibility) now and then, though I don't really understand how that happens (unless options get renamed?).
I also only had one run so far with the new scheme, and focus seemed clearly better than before. I'd like to get some more data, including focus debug messages....
