After upgrading my machine to Monterey, if I choose to "Rebase children of...", the unselected commit entries in the window that is displayed are black text on a black background (see attachment).  This makes it slower to do interactive rebases.  This was happening on 4.1.4 - but is also currently happening on 4.1.5 (but I can't select 4.1.5 under "Affects Version/s" as it isn't yet published there).
