Log file: steam-668580.log that goes up to the difficulty selection where the first missing videos are.

Symptoms

None of the in-game videos work. There should be some on difficulty selection but they're blank.

There should also be videos on various screens on the game, they also don't play but you do hear the audio.

Reproduction

Just try it with Proton, get to the difficulty screen when starting a new game, and notice the black boxes above the options.

It has also now been given a "Steam Deck Playable" rating, but since videos in-game are broken, it shouldn't even be set as Playable should it?

Reproduce the issue on Steam Deck with Proton 7.0-6 by reaching the difficulty-selection screen, then inspect the linked steam-668580.log, which covers the first missing videos. Trace Proton's video/media handling from the log; done means the in-game videos render while their audio remains functional across the reported screens.
