Hello, I may not be related, but I had a similar issue (infinite loading) with only the first 3 lines of your logs.

My solution was to use Intel graphics instead of NVIDIA (on Ubuntu, with __NV_PRIME_RENDER_OFFLOAD and __GLX_VENDOR_LIBRARY_NAME shell variables).

Hello @sebmestrallet
If you are running latest Mayo version(built from develop branch) then you should have access to Help->System Information command(see #210)
Could you then please post here the whole information with your NVidia device on
Post as well what you get with Intel chipset on(maybe only the "OpenGL" related infos)
Thanks!

I tried to install from sources (I used the AppImage before), but sadly Qt 5.14 is not available on the Ubuntu 20.04 LTS apt repository. And I don't have the rights to add PPAs on my PC...

I forgot to say in my last message that the warning/error lines are still printed with Intel drivers but it works.

Some news: I have another work PC on my hands, on Ubuntu 22.04 this time. The build instructions for Debian work perfectly. I no longer have any problems with NVIDIA drivers. Here is the System Information output, OpenGL parts.

With Intel graphics drivers:

I still have

DEBUG: OpenCascade settings file doesn't exist or is not readable [path=opencascade.conf]
TKOpenGl | Type: Other | ID: 0 | Severity: Medium | Message:
  OpenGl_Window::CreateWindow: window Visual is incomplete: no stencil buffer

warning lines printed at runtime in both cases.

Hello @sebmestrallet
Good to see it works on your side, thanks for the feedback
That TKOpenGl message is an OpenCascade warning and shouldn't cause rendering problems(see comment)

@physnoct
Are you still having the issue? What about the 3D graphics, do you see the STEP file correctly rendered?
