Ah someone who is suffering from wine not supporting single buffering anymore.

Near line 437 in dlls/winex11.drv/x11drv_main.c you'll see:
    /* If OpenGL is available, change the default visual, etc as necessary */
    if ((desktop_vi = X11DRV_setup_opengl_visual( display )))

try to skip that line by changing it to lets say:
    /* If OpenGL is available, change the default visual, etc as necessary */
    if (0 && (desktop_vi = X11DRV_setup_opengl_visual( display )))
