Weird Pattern Shift
Same issue here.
Did you update the spatial latent_upscaler to 1.1?
The speed gain is great but the quality loss is not worth it... Yes Im using the upscaler 1.1.

I just gave it a go too and SAME issue. Went from 55 secs for a 1280x720 gen to 45 secs, which is a nice time cut BUT... hope they fix the quality loss ;)
Same issue here.
I get the same behavior on very long videos (+30s) with the FP8 model. I have tried to solve it with more steps like I have done with WAN2.2 videos when I get odd artifacting, but at least in my simple testing that hasn't seemed to help.
Other than the quality loss, which I have too, in many prompts the outputs are in slow motion, on FP8 sometimes there are head spinning issues but NEVER slow motion... I do not have on the FP8 model generating 20secs in 1280x720.
I really like LTX2.3, being able to gen in 720p, 20secs and with audio is great I really do not want the slow motion problem from Wan 2.2 on LTX2.3. I hope it can be fixed otherwise in my opinion is worth waiting more time for each generation.

Yeah,.. but I think the issue is probably relative to me just prematurely trying to run NVFP4 with the same setup as the dev and fp8 models. There's probably other loras and encoders that have to run along with it. IDK... I'm slowly learning how to use all of this... painfully slowly.
