When attempting to play some types of videos with VLC 3.0.16 (eg. *.flv, *.mp4), when running kernels 5.17-rc1 to 5.17-rc3, only the audio portion is heard and the VLC video screen remains black. Meanwhile, many of these entries are written per second to /var/log/syslog:

The problem doesn't occur in kernels of the 5.16 series.  It may have been introduced here:
