It seems to have broken that fix, of course you can still disable it, but it doesn't seem to remove the stutter sadly... and I think the HDMi Device Link is a cool feature so its annoying to disable it! You can probably keep it enabled for now.
I tried just about every combination of setting on the TV and PS5 and I could not fix the stutter... So I think this is now in the hands of Roku.
Dude you are the man! Kind of comforting to heat it’s not just me experiencing this. It’s totally the new update that’s causing this. Hopefully it’ll be fixed soon! Keep updated if you find any solutions or if Roku gets back to you
Still stuttering on my end. I even tried to have TCL support try to help me factory reset it to before 10.0.0 but we can't find a physical reset button on my model for some reason. I'm like 99% sure it's the OS update at this point.
