https://bugs.winehq.org/show_bug.cgi?id=38652 --- Comment #1 from Jason <jasonwinter(a)hotmail.com> --- I'm unsure, since my code is designed for windowless & windowed renderers, but SetWindowPosition should either do nothing in windowless mode or move the clipping window (not the Wine window implementing VMR9). Once the Owner is set, I can see the video window (class "IVMR9 Class") move inside the clipping window as this function is called. I think these differences are because Wine creates its own window for VMR9 windowless rendering, where Windows actually paints into the clipping window. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
