    Avid Media Composer 2018.12.15 - Playhead is jumpy/stutters

    Does anyone know what could be causing a stuttering/jerky timeline playhead? Everything is playing fine, but the playhead stutters along the timeline.

    I’ve rebuilt my settings again this week and it subsided for an hour or so, but as soon as I got into more complicated edits it returns.  All my media is imported as DNx36, I've tried disabling the DNxID and it has not helped.
    Everything is working, just an annoying sputter as the curser moves that makes it hard to jump on a transition or see the timeline properly as it plays.

    Hardware:

    • 27" iMac Pro (2.3 GHz 18-core Intel Xeon W, 32 GB ram, Radeon Pro Vega 64, Retina 5K display)
    • 2nd 27" LG 4K display
    • DNxID for audio/client display.
    • SANDISK PRO G-RAID 2 HARD DRIVE - 8TB" as his media drive.

    Software:

    • SmacOS Mojave 10.14.6
    • Avid Media Composer 2018.12.15
    • Continuum 16.0.3
    • Blackmagic Desktop Video 11.6.

    I am not Mac aware, I would suggest turning off any programs running in the background, dissabling any power budget schemes.

    Usually due to programs competing for system resources.

    Using MC 23.12. Win 22H2  Avid FX6.4, Vegas Pro 20/ DVD Architect 6pro, DVDit6.4proHD, CCE Basic, TmpGe Express4, TmpGe Authoring Works 4, DVDLab-Studio. Sony EX-1R, Canon XH-A1, GL2, GL1, Canon EOS 60D
