https://bugs.winehq.org/show_bug.cgi?id=45724 --- Comment #2 from Andrew Wesie <awesie(a)gmail.com> --- Is the concern that applications may expect EndScene (without a Present call) to flush the pipeline and they can rely on that instead of using the D3DGETDATA_FLUSH flag for queries? While I haven't found an authoritative source regarding EndScene and flushes, a random forum post (https://www.gamedev.net/forums/topic/620095-present-without-actually-present...) states that: "without calling Present() you can't be sure that after EndScene() the GPU will flush the pipeline" I agree that a unit test demonstrating this behavior would be ideal. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
