Zebediah Figura (@zfigura) commented about dlls/ddraw/ddraw_private.h:
struct wined3d_stateblock *recording, *state, *update_state; const struct wined3d_stateblock_state *stateblock_state;
- /* Vertices Buffer for squashing DrawPrimitive() calls before sending it to wined3d */
"Vertex buffer", and please end it with a period.
