Comment # 2 on bug 1214211 from Steffen Winterfeldt

AFAICS, happens only when plymouth is active.

No issues with plymouth=0.

Could even depend on the specific plymouth theme used.

You see it when you press ESC briefly after the first plymouth screen
appears.

It's this way at least since 20221206 (my oldest TW iso I kept) and also
in Leap 15.4. But not in Leap 15.1.

Really, no idea.

Reassigning to plymouth maintainer.
