Bug ID: 45882
           Summary: (Overwatch, several source games) Raw Mouse input not
                    working
           Product: Wine
           Version: 3.16
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Playing Overwatch I've noticed that the game still uses mouse pointer speed
even though on Windows it uses Raw Mouse input exclusively.

I've tried this on any branch of Wine (staging, esync, whatsoever) and the
problem still persists. This also happens in Valve games where you can enable
Raw Mouse Input, e.g. Team Fortress 2 etc.

This does not happen with the native ports of said games that use SDL to get
mouse input.

I already disabled any mouse acceleration in GNOME whatsoever (using the "Flat"
Profile), however the problem persists.

Is it possible to rewrite Wine to get Mouse input via SDL2 instead? That would
help pave way for Wayland etc.

Thanks
