When setting DirectDrawRenderer to opengl the screen flickers and partially updates, making graphics look bad.
Apps affected: All games exported from windows version of Blender 2.45.
Hardware affected: ATI R200

Steps to reproduce: Install Blender 2.45 under wine (or in windows). Create a very simple game and export to .exe format. Open up regedit and set DirectDrawRenderer to opengl. Run the game under wine.
Result: Flickering, tearing, page flipping not updating, See attachment

--- Comment #1 from Roderick Colenbrander thunderbird2k@gmx.net 2007-12-23 12:49:03 --- If the problems don't appear on nvidia hardware it is a driver bug. Also opengl is not the holy grail on improving ddraw performance in Wine. It depends a lot on in what way the game is using ddraw in the first place. Even when it uses ddraw in a 'opengl-friendly' way you in general need special opengl extensions like GL_ARB_pixel_buffer_object to unlock the real acceleration. In general opengl is worse or equal to gdi.

--- Comment #3 from Henry nospam@thenerdshow.com 2008-08-09 13:32:35 --- This was caused by "Sync to vBlank" (linux driver setting) and it happens on nVidia too when playing blender-generated games.
If this kind of graphics corruption is expected from sync setting, we can mark this bug as WORKSFORME.

--- Comment #4 from Henry nospam@thenerdshow.com 2008-09-04 00:06:12 --- No, I was wrong. It has nothing to do with graphics driver's 'sync to vblank' setting. I just upgraded to wine 1.1.3 from git today. I am getting blank blue windows using opengl. I have to set DirectDrawRender to gdi in regedit to play Blender-generated games.
