Asunto: [devuan-dev] bug#433: vlc-plugin-qt: VLC Qt UI doesn't start in the presense of QT_QPA_PLATFORMTHEME, GTK_CSD and LD_PRELOAD
Package: vlc-plugin-qt
Version: 3.0.8-0+deb10u1
Severity: grave

Dear Maintainer,

I have all my Qt 5 applications rendering their UI via GTK2
(this means I have qt5-style-plugins package installed):

> QT_QPA_PLATFORMTHEME=gtk2
> QT_STYLE_OVERRIDE=gtk2


Additionally, for my GTK3 applications, I have client-side decorations
disabled (with gtk3-nocsd and libgtk3-nocsd0 packages installed):

> GTK_CSD=0
> LD_PRELOAD=libgtk3-nocsd.so.0


The above should have nothing to do with GTK2 UI rendering, still it
affects vlc (actuallly, vlc-plugin-qt) in Debian Buster/Devuan Beowulf
(everything worked fine in Debian Stretch/Devuan ASCII).

Also, I have to mention that cvlc (without Qt UI) works fine.

Now, to the problem.

Whenever vlc is laucnhed in the above environment:

> $ QT_QPA_PLATFORMTHEME=gtk2 QT_STYLE_OVERRIDE=gtk2 GTK_CSD=0 \
> LD_PRELOAD=libgtk3-nocsd.so.0 vlc


-- it prints the following and just hangs, w/o even showing a
window:

I can also provide the output of `vlc -vvv` here, but it wouldn't be
indicative, as, the above errors are purely GTK-specific.

*If* I change either GTK_CSD to 1 or LD_PRELOAD to an empty string (or
Qt UI style to anything different from gtk2), then vlc starts just fine
and shows its window, controls, etc.

All other (even complex) Qt 5 applications (assistant, designer,
wireshark, KDE appplications etc.) are not affected by either GTK_CSD
or LD_PRELOAD.

The problem is reproducible using a new clean user profile with default
vlc settings.


Regards,
Andrey.
