Artifacting at end of video with LTX-2.3

[q5sys]

I'm noticing this in just about every video I generate, in the final second and the image will have a bright flash over some part of the video, It happens on both Vertical and Portrait aspects. It almost looks like its an overlay graphic that's being added at the end for some reason.

I've attached three examples to help explain what I'm getting since I dont really know how to describe it. I never saw this with LTX-2, only with the newer LTX-2.3 release.

I experience the same, but with a different style of artifact. Doesn't always happen, so im guessing its certain tokens in the prompt that pull this in?

I'm getting this too, almost every video that I generated has this artifact near the end. Sometimes, it looks like a bright watermark. There are times it looks like a bright distorted title or logo. It's driving me crazy, I tried so many settings and is still the same. Did you managed to fix it?

The only resolution I've found is to end my prompt with something that has little motion for a second, like in a explainer video I'll put, "The person stares at the screen for a few seconds and smiles."
That along with increasing the frame count by 25-50... lets me cut the end of the video in post processing.
It's not a fix, but it at least gets me segments I can use.

I been getting different logos and ending animations at the end of the videos similar to this issue, only on LTX 2.3 - happens in almost all of the generations.

Same issue. Relevant discussion here: https://huggingface.co/Lightricks/LTX-2.3/discussions/13. I tried with the new sigmas and I think they help a little. But I still see some artifacts.
