VLC video playback issue on uConsole fixed by downgrading raspi-config
After a system update on my uConsole (Debian 12, labwc), I noticed that video playback in VLC became choppy, even with low-resolution videos that used to play smoothly.
I reviewed the list of recently updated packages and tested a manual downgrade of raspi-config, which immediately fixed the video playback issue.
Rollback to the previous version of raspi-config (20250618):
wget http://archive.raspberrypi.org/debian/pool/main/r/raspi-config/raspi-config_20250618_all.deb
sudo dpkg -i raspi-config_20250618_all.deb
sudo apt-mark hold raspi-config
After downgrading, VLC playback is smooth again, and everything works as expected.
