You're right. But, at the same time, as I mentioned in the original report, other Qt-based applications are unaffected by the presence of libgtk3-nocsd0 in LD_PRELOAD. And, additionally, the issue is not reproducible in the vanilla 3.0.8 version of vlc built from source. So my suggestion is this has something to do with either Debian packaging and/or custom patches. As I said, I'm running Devuan 3 (Beowulf) which uses packages from Debian Buster unaltered.
