Reproduction

Just run the game, no extra tweaks needed.

Start by reproducing the missing cinematics with stock Proton 5.13-1, then compare the behavior with Proton-GE-5.9-ST-8 and DirectX 11. Inspect the attached steam-1186640.log and the listed MPEG-4 media details; done means the game's cinematics play correctly under the affected configuration.
