New description:

 Some chroma artefacts randomly appear on decoded VVC streams using ffmpeg
 (or ffplay). The artefacts do not appear using the reference VTM model
 (tested on VTM-23.3) nor with any VVC-compatible stream analyzer.

 How to reproduce:
 {{{
 % ffmpeg -i Visual720p_QP1000000.BIN visual_1280x720.yuv
 ffplay version 7.1-full_build-www.gyan.dev Copyright (c) 2003-2024 the
 FFmpeg developers
 built with gcc 14.2.0 (Rev1, Built by MSYS2 project)
 }}}
