Occasionally, after log in, I lose access to my session

Occasionally, 20 s after login, I shall be brought back to SDDM. There, when I log in again, I shall observe a black screen, until I manually switch TTYs to my session.

I have noticed that this might coincide with, because it has recurred this session:

However, this definitely occurred after bugzilla.redhat.com/show_bug.cgi?id=2411800#c37 did. Unfortunately, due to a persistent recurrence of bugzilla.redhat.com/show_bug.cgi?id=2416690, I’ve no Konqi report to accompany this, if it is relevant.
