Thanks, I missed it at first glance.

I modified the d3d9 occlusion query test to check if it gets flushed
implicitly, flushed implicitly with BeginScene / Draw / EndScene, and then
flushed explicitly. This revised test passes on my Windows 10 x64 installation
when using Intel GPU. It does not pass with AMD GPU because the query is
flushed implicitly (e.g. even without the BeginScene / EndScene).

With my previous patch to wined3d query and the attached patch to remove
glFlush from wined3d_device_end_scene, the revised test also passes on Wine.
Obviously without removing glFlush from wined3d_device_end_scene, it does not
pass.
