--- Comment #4 from Michael Stefaniuc mstefani@redhat.com 2012-07-05 15:32:38 CDT --- Thanks but I do not see the assert in the logs. That's important as I'm trying to figure out what the "invalid" interface passed to d3d9_device_SetStreamSource() aka IDirect3DDevice9Ex::SetStreamSource is. It should be a IDirect3DVertexBuffer9 created by Wine or NULL but it isn't. Also I can most likely see who passes us that interface, Wine or the application.
