I'm quite sure that if the add-on runs when Kodi is in the Home page, there are not such GUI refresh issues; on the contrary, if you are in any other page, you can just turn off in the add-on settings the progress update status so that this will solve your problem.

You are right, of course, that there is no refresh issue in the Home page. But since I like to use Kodi while other stuff is going on instead of patiently waiting I usually go to, say, a YouTube favorite and watch their latest streams. That is where the problem is coming in because it is very difficult to get any object to play because the constant refreshes keep cancelling the "Play" keypress. For this, it does not matter, unfortunately, if the Ratings add-on is set to run in the background (which it is, I like to run stuff like this with as little impact on the GUI as possible for the reasons explained).
