Lightroom Classic hangs for 4 sec after playing a video

When in the Loupe view, if I play a video, I can't move to another image or video for ~4 seconds.
I get the coloured spinning ball and Lightroom isn't responsive.

Here's some common things I've noticed:
  • It usually happens after I've already played 5 or 6 videos first. The first few videos played work just fine.
  • It happens on both MP4 and MOV files.
  • The video resolution is usually 1080p 29.97fps, I haven't shot 4K (yet).
  • If you're sorting through a bunch of <10sec videos, having to wait ~4 sec before you can move to the next one is quite frustrating.
  • There's no delay moving between videos/images if you don't play the video. It's only if you play the video. The delay happens if you move to the next video/image any time during playback or stopped playback, as long you've actually played the video.
  • Nothing else on my system does this with videos - Apple Preview plays them just fine one after another.
  • LR has been doing this for ages - I think maybe since LR7? It's finally gotten annoying enough to complain, and other LR competitors now getting better I decided to see if I can fix my personal LR complaints before investing precious time looking elsewhere.
  • I usually run LR in the MacOS full-screen mode.
  • It doesn't matter if I turn off graphics acceleration in LR or not. Same experience.
  • I've cleared my video cache, and also re-installed MacOS plus Lightroom completely without restoring from a Time Machine backup (so a fresh preferences file too), and it reoccurred.
  • I've replaced the original Apple 512GB SSD (2x PCIE) with a 1TB Sabrent SSD (4x PCIE), didn't make any difference.
  • The delay doesn't get any longer than 5 seconds, like it doesn't get slower and slower, even if I use LR for an hour or more working with video (painful).
  • I can skip forward and back in the video with no delay. There's no delay pausing and playing either, just moving to the next/previous image/video.
Not sure if worth noting, videos don't play in Lightroom full-screen for me (i.e. by pressing the "F" key), I simply see the thumbnail of the video. The audio plays though. Again this is also whether I have graphics acceleration on or not.

Also, sometimes instead of freezing, Lightroom will simply stop updating the Loupe Preview window - the filmstrip down the bottom will show it's moved onto the next photo/video, but the Preview is still showing the last frame of the video that was just played. I have to go to Grid then back to Loupe to get it to update.

I have a similar issue, I'm on Windows. It does it virtually every time I look at a video. Don't have to have been looking at several before hand. 

As you say it has been an issue for several versions on LR.
