Hi,

thanks for the info. Anyway, I am little bit confused how sharing of contexts should look like.

Yes, I can store context for sharing e.g. in init() handler, but when I want to share contexts between more canvases before they are displayed, I cannot see a way how to do it.

Also when moving canvases in the hierarchy (removing and adding them from/to a container) can possibly destroy all existing contexts which means that sharing won't suffice and textures, display lists, etc. will be destroyed.

Summed up: exists there a way how to create a context that can be seamlessly used for sharing between multiple GLCanvas instances?
