Developer HUB and Cinematic casting Stuttering effect

I've been trying to get into creating content for the Quest and have been using the 1:1 casting (using OBS to capture) and just stretching and cropping the image into a 16:9. It works... okay, but I figured there had to be a better way. SO I found the Developer HUB and the CAST button there will allow a "cinematic" cast. However when I enable that I get a stuttering effect when I move. I've messed around with the refresh rates and everything but no matter what I do, it still stutters as I move. Plus, after reconnecting the cast a second time the Menu is grabbed and loses spacial tracking (just staying in front of me all the time).   I'm not sure if I'm doing something wrong or if this is just "how it is" with this mode.  My headset is also on Firmware 72 but it's not updating to 74 yet so not sure if that fixes this or what. It doesn't seem like I can "encourage" it to update either.

Anyone else know a "fix" or workaround? Hopefully Meta gets it working if that's just how it is. Would make it a lot better content to share videos.
