This seems to be an widespread issue with Windows 11 24H, as it also affects Silent Hill 4 - https://www.gog.com/forum/silent_hill_4_the_room/fmv_cutscene_colour_now_broken/post4
I have no idea what Microsoft and their vibe coders are doing they managed to break another thing and who knows what other games are affected.
I'm not using Xinput Plus, or the Audio Enhancement pack and I'm running the game on Windows 11 24H2 and the intro movie of the game is black with the sound still playing when enabling "ReplaceMoviePlayer".
When disabling ReplaceMoviePlayer the FMV has artifacts and and wrong colors (see the attached screenshots).
This is with the latest version of the Fix (2.7.5) but also happened with the previous version.
Anyone know how to fix?
