I just installed KDE minimal from KDE 20.2-rc4 ISO using Architect on a laptop. Now kitty is not started any more when log in. But I can manually start kitty and works normally. So just the autostart feature is broken.
If log in from boot or reboot, everything is fine.
If log out and log in again, after typing password, the screen is hanging on the progress bar at about 80% for even a few minutes! And all 3 programs appear on desktop 1, not on designated 4 and 5.
