For me it is ALWAYS vlc, and it has been doing this at random for the
past year or two. No solution other than "killall -KILL vlc" now and
then and especially before leaving for the night. I don't know what
triggers this behaviour, it doesn't always leave stray processes
around.

Maybe some day I'm annoyed enough to file a bug report. This happened
with different GPUs, different monitors, Wayland vs. X11, and I see
this on Gnome in Debian testing.
