Graphic not rendering in VNC desktop environment

[eldplanko]

I'm having problems with graphics not rendering correctly in my VNC desktop environment.

Background:

Fresh install of Xubuntu 22.04 Desktop in Proxmox virtual machine.

CubicSDR build from source, using build typical build instructions: (https://github.com/cjcliffe/CubicSDR/wiki/Build-Linux); wxWidgets-3.2.1

CubicSDR runs correctly in native Xubuntu desktop environment console (xfce4) (i.e. VM web based console), graphics for spectograph, waterfall, bookmarks toolbar, etc render correctly:

If I connect to xfce environment through VNC, CubicSDR starts correctly, but wont render graphcs for spectograph, waterfall, etc.. I suspect something with how I'm setting up my VNC, but wanted to check here for any thoughts.

Looks like this is similar to #870, where wxWidgets wont render in VNC because of OpenGL. If this is the case, why does it render in the Proxmox web-based VNC (noVNC)?

Closing, was able to pass through hardware acceleration with X11VNC.
