Mdegrain3 Line Artifacts #62

I have been using your MVTools for a while with great results. However, recently I encountered some issues. I encoded a video and noticed some weird horizontal line-type blockings. It’s not banding, but when a cloudy-type object covers a wide area and moves, it looks like multiple horizontal lines of box-type patterns appear and it shows up on multiple parts of the video. It's not present in the source file and isn't coming from any other prefilters used before MDegrain3. When the video goes through MVTools and removes the grain, the issue appears. I am facing this issue recently and have tried everything to solve the problem, but nothing has worked. I also used the latest and many other versions of MVTools, but the issue persists.

My Setup: AMD Epyc Processor; Windows 10 Server Edition 2019 AviSynth+ 3.7.3

All the source, avs, test files and images are included. Link

Encoder Used: x264 (veryslow preset)

Please look into the matter kindly and inform me Thank you.
