don't let vbo destory all
using a vbo destroys the existing context, hence how to avoid such?
Since when do VBOs destroy anything? Nothing is destroyed. What are you talking about?
I do a plugin, vbo is ok but everything else from the parent is gone. I would appreciate advice on how to save and restore the original.
You're talking completely incoherent nonsense - pretty much like in the other thread you opened on this "plugin". Please be more accurate.
What do you mean by parent? The application dynamically loading a dynamically loaded library?
Just to be really clear to you.
This behaviour you get is not part of the way OpenGL behaves. You have a bug (or oversight/omission) in your own code that's causing it, and without seeing your code it's impossible to even guess what that bug/oversight/omission might be.
Yes after commenting:
it works! Honestly I don't know what the above was for...
