Perhaps the issue lies in the fact that you have initialized a new OpenGL context here once again, which might be conflicting with the existing one.

I'm trying to expand the example by moving the 3D interactive scene into a floating window. My understanding is that this requires OCC to render into a buffer and then
imgui::Image(or similar functionality) to render the buffer into the GUI. However I'm getting stuck.I've imported a new class adapted from here OffScreenRenderer. I initialise it but then I get an OpenGL error when I try to render the image into the buffer with
ToPixMap.@gkv311 maybe you can help me. Do you know if the error comes from the fact that an application cannot have on-screen and off-screen renderers at the same time? Or perhaps because I'm using a general
Aspect_NeutralWindowfor the off-screen renderer?
