#Qt signals in a #NukeStudio tool I wrote don't reach my background thread anymore. Worked fine in Nuke 13 (Qt 5.12, Python 3.7) and no longer works in #Nuke 14 (Qt 5.15, Python 3.9) unless I connect the slot as a DirectConnection (i.e. just call a function across threads).
Search engines are useless for those keywords. How is one supposed to debug this? Read every changelog between those versions?
