I built vlc but there isn' t any interface (linux)

I used apt build-dep vlc I installed all libvlc- packages. I also installed all the packages of the guide https://wiki.videolan.org/UnixCompile.

I built vlc 3.0 since the 4 required an high version of qt.

vlc -l | grep face
VLC media player 3.0.3 Vetinari (revision 3.0.3-1-0-gc2bb759264)
  lua                    Command-line interface
  lua                    Lua Playlist Parser Interface
  motion                 motion control interface
  gestures               Mouse gestures control interface
  dbus                   D-Bus control interface
  xcb_hotkeys            Global Hotkeys interface
  dummy                  Dummy interface
  hotkeys                Hotkeys management interface
  oldrc                  Remote control interface
  vdpau_chroma           VDPAU surface conversions
  vdpau_chroma           VDPAU surface conversions
  skins2                 Skinnable Interface
  skins2                 Skinnable Interface
  qt                     Qt interface
  qt                     Qt interface
  ncurses                Ncurses interface
  glconv_vaapi_drm       VA-API OpenGL surface converter for DRM
  glconv_vdpau           VDPAU OpenGL surface converter
  glconv_vaapi_x11       VA-API OpenGL surface converter for X11

vlc -I ncurses opens a "terminal" interface that is nothing more then the cli. ncurses interface

Now vlc or (vlc -I qt) get:

vlc

Edit: If I run env QT_AUTO_SCREEN_SCALE_FACTOR=0 vlc it works but it is not comfortable. How can I fix it? I cannot launch it from the applications or open with vlc.
How can I change the default interface (qt) to for example skins2?

Solution

Add QT_AUTO_SCREEN_SCALE_FACTOR=0 to the file /etc/environment if it exists, if not create it and reboot!
