My problem is, that somehow when I create a new Window (keeping the old one setting it inactive), textures that get loaded by the GUI-System I use won't show anymore.
If I simply recreate the existing window, this problem does not occur.
So I assume there might be some fundamental difference between creating a new and recreating an existing window. What about the RenderContext? When recreating a window, there is also a new RenderContext created, isn't it? So that would be the same for creating a new and recreating one?
Thank you for any hint.
