Yes, opengl does not have the concept of video memory like DirectX has. OpenGL
implementations can work without video memory, for example mesa software
rendering, or rendering using a remote opengl server.
On implementations with video memory, the opengl driver has to take care of
that. The way it does that is transparent to wine and the applications.

It doesn't have to be caused by opengl at all.
