Wings3D running in VirtualBox [Linux]

I think we may need to try find any relation between the desktop environment in use in these distros...

Ubuntu is available in various desktop environments like:

• Ubuntu prior to 18.04 LTS =>Unity8 desktop environment by default
  
• Ubuntu 18.04 LTS and newer => GNOME desktop environment by default
  
• Ubuntu MATE (MATE - is the continuation of GNOME 2 by a new community that was dissatisfied with GNOME 3)
  
• Xubuntu (XFCE - is based on GTK+ version 2),
  
• Kubuntu (KDE Plasma)
  
• Lubuntu (LXDE)
  
• Ubuntu Budgie (Budgie - uses GNOME technologies such as GTK+)

Debian 10 "buster" ships with several desktop applications and environments. Amongst others it now includes the desktop environments:

• Cinnamon 3.8
  
• GNOME 3.30 (default)
  
• KDE Plasma 5.14
  
• LXDE 0.99.2
  
• LXQt 0.14
  
• MATE 1.20
  
• Xfce 4.12

In this release, GNOME defaults to using the Wayland display server instead of Xorg. Wayland has a simpler and more modern design, which has advantages for security. However, the Xorg display server is still installed by default and the default display manager allows users to choose Xorg as the display server for their next session. (reference)

nigec, maybe you can switch from Wayland to Xorg and see what happens.
