Same happens also if I just lock the screen META+L and try then to log in. Am using the Wayland session if that matters.
Comment 2 foss 2019-10-13 09:23:30 UTC 
Problem seems to be solved by updating frameworks to version 5.63. At least I can't reproduce it anymore after frameworks 5.63. Sorry for the noise.
