I'm not sure whether you're saying it is, but note that context 0x65f87d0 is
not new:
> 00f8:trace:d3d:wined3d_swapchain_gl_create_context Creating a new context for swapchain 0x65dcc00, thread 248.

Note also that nouveau is known to have some issues with using multiple GL
contexts. That's not generally an issue for wined3d because the command stream
serialises GL calls, but would be for applications that use multiple D3D
devices concurrently. A quick test would be to force usage of llvmpipe by
running with "LIBGL_ALWAYS_SOFTWARE=1" set.
