Some games calls IMFMediaSession_Stop while the presentation is ending, expects that command to quickly execute, interrupting the presentation end and emitting a MESessionStopped event instead of the MESessionEnded. Delaying the Stop command and emitting the MESessionEnded event breaks the game assumptions and it crashes, or waits for the MESessionStopped event forever. This is a redone of https://gitlab.winehq.org/wine/wine/-/merge_requests/1710, which still appears to be necessary for Disintegration. Haven't tested Life is Strange again, but I suspect it's probably some quirks of some Unreal Engine version. -- v2: mf/session: Discard end of presentation on IMFMediaSession_Stop. https://gitlab.winehq.org/wine/wine/-/merge_requests/9897
