Adding Gerd Möllmann.

The flicker appears to have been introduced by the work done in 414de92a562

Initial child frames based on master (Mon Oct 21 18:32:04 2024 +0200, 5
months ago) <Gerd Möllmann>

It's a fairly large change set, so I don't know yet what might be causing
it. I can reproduce it fairly consistently using my own setup, but I don't
know how to narrow it down to something from Emacs -Q because it appears to
be related to CPU utilization and/or rapid updating of buffers that are not
currently visible.
