jankomack: Final update from GOG support regarding the FMV color issue
I’ve been in contact with GOG technical support for several weeks now, and here’s a summary of their latest response and what I’ve tested:
They suggested:
Performing a clean driver reinstall using DDU (done – no change).
Trying the Steam006 unofficial patch → the author himself confirmed that “Windows 11 update KB5064081 (August 29 2025 Preview) broke FMV playback.”
Using the 16:9 FMV Pack → it only changes aspect ratio, not colors.
Running the game in clean boot mode with all non-Microsoft services disabled.
Launching via DxWnd in borderless windowed mode.
Testing the Nemesis wrapper as an alternate fix.
All of these steps were tested. The FMV color corruption still remains exactly the same.
At this point, it’s safe to say that the issue is not caused by GOG, the patch, or GPU drivers, but by recent Windows 11 updates (KB5064081 / KB5064801), which broke FMV decoding.
Other users have confirmed identical results.
Everything else in the game works perfectly – only FMV cutscenes are affected.
Unless Microsoft releases a hotfix, there’s unfortunately no working solution yet.
Thanks to GOG support for their patience and effort. For now, I’ll wait for a Windows or GOG update that restores proper FMV playback.
Nothing new here. GOG support can offer more than just the usual troubleshooting solutions. They should escalate the issue to the GOG Preservation team, as only GOG could "urge" Microsoft to resolve this issue.
