           Summary: Overwatch 2 fails to save highlight video files
           Product: Wine
           Version: 9.0-rc2
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

When attempting to save an Overwatch 2 highlight video as an mp4 file (the
default format), it fails with this error message:

SAVING ERROR
An unknown error has occurred. (6-04)

Steps to reproduce:
- play a game (easiest way is via Play: Training: Practice vs. AI: Casual)
- after the game is over, return to the main menu
- click username button (top right corner)
- click history tab (top edge)
- click highlights tab (left edge)
- click a highlight from "today's top 5"
- click save button (bottom edge)
- select movie format: mp4
- click save button

Note that this is a different kind of failure than the one with .webm format
(bug 56059).
