Description
Regression in the 3d FFT Denoiser filter in libavfilter, with ffmpeg 5.0.1 as shipped with Kdenlive 22.08.1 (AppImage). When rendered, the bottom lines of the video are corrupted and are black, green, or garbage data.
How to reproduce:

This seems to be a regression because 4.4.2-0ubuntu0.22.04.1 does not have the same problem.

Please test current FFmpeg git head, the only version supported on this bug tracker, and provide the command line you tested together with the complete, uncut console output to make this a valid ticket.
