Symptoms

1. Game crashes to desktop after a few minutes of playing.
2. Menu background doesn't play, it shows as a white screen.
3. Video cut-scenes don't play during loading screens.

Reproduction

1. Playing any of the campaign missions for 15 minutes (sometimes less) with esync enabled. If esync is disabled the game won't crash.
2. Launching the game and reaching the main menu. Installing the Media Foundation DLL solves this issue.
3. Starting any campaign mission. Like issue above, Media Foundation DLL solves this.

Notes

The attached log was captured with esync enabled but with the Media Foundation DLL installed.

Start with steam-620590.log and the linked system information report, using Proton 5.0-6 with esync enabled. Reproduce the campaign crash and the white menu and missing cutscenes, comparing behavior with esync disabled or Media Foundation DLL installed. Done means the cause is isolated and the game runs without those workarounds.
