In this case, it seems to be a bug in the VLC Qt Wayland support which is 
notoriously broken. To be fair, the VLC 3.0 configure script does state:
 "Incomplete Wayland support (default disabled)"

It was probably not a good idea to enable it in Debian. VLC 3 should be used 
through XWayland.

Wayland support is spposed to be better with the upcoming vlc 4.0. No
idea when that version will be released, though.

Bug#983250: vlc: Crash when starting to play video under weston / wayland

[Witold Baryluk]

Package: vlc
Version: 3.0.12-2
Severity: normal
X-Debbugs-Cc: witold.bary...@gmail.com

I just decided to try wayland again for the first time in years, and test some 
apps.

mpv works.

vlc doesn't.
