(Mac 7.2.3874) Judder on Pro Display XDR at 47.95Hz refresh

On Pro Display XDR, powered by a clamshell (built-in screen OFF) 14" MBP with M1 Max, I am seeing judder when playing back 23.976 fps movies which should have a perfect frame cadence and no pulldown or judder.

The judder isn’t consistent, in that I can re-watch the same scene many times and the judder happens at different points, may not happen at all, etc. Happens in window or full screen so it seems distinct from the judder being reported on the ProMotion displays.

Please let me know what I can provide in the way of diagnostics, files, etc.
