Comment 4 for bug 1793242

This is pretty much how it has always been, but I never had the time to properly analyse it and report it to the KDE devs (just found this report here while searching for it, because I got annoyed again).

Overall, the session restore mechanism seems to be insanely buggy. Chrome is never restored, KDE apps are almost always restored, other Qt and Gtk apps seem to be hit and miss. Sometimes it restores KDE applications that were closed long before I ended the session. This time it was QtDesigner that popped up although I closed it before logging out. I wish this worked more reliably. I hate to say it, but macOS does it perfectly, almost like I never shut down the PC.
