Boris, The Katzeye screen may be not seated completely right. If you accept to take the risk (but is it really a choice?), I'd remove the Katzeye and reseat it. If not better, I'd put back the genuine screen and try again.
Getting there, you should be able to determine if the problem is one of the screens or the way there're seated. If not, a calibration from Pentax would be best IMO :( In the meantime, you may use LiveView for focussing the 50/1.2. I agree this is not a desirable solution but better than no LiveView at all.
