--- Comment #2 from Priit priit@ww.ee --- i Timeshifted back and it works. And put it into pacman ignore list. and reapplied all the other updates to like 370+ packages again (except wine-staging) and HDT still works (with wine-staging 5.8-1 then) so it has to be the 5.9-1. There is no wine 5.10 in manjaro repos yet. Not going to try any unstable branch stuff, but when 5.10 comes into stable repos, I will let you know.
"Does not work" did mean this time, that the initial HDT logo "Loading..." thing did stay on screen forever and never reached the loaded / functional status.
