This isn't a major issue, just an annoyance - when Tixati does its update check and finds a new update, the popup window steals focus, even from fullscreen applications. Is there something I can do about this besides turning off the automatic update check?

I think a change to the z-level only for Tixati as active window makes more sense than a global z-level max, +1 here.

It's the same for the donation nag screen .
