Bug ID: 49423
           Summary: Added input lag in World of Warcraft and other games
           Product: Wine
           Version: 4.17
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

In World of Warcraft you use WASDQE to move your character in the world in a
very highly responsive manner. When using WINE 4.16, there is no perceptible
input lag. However, switching to WINE 4.17 or higher (verified in 5.7 also),
there is immediately perceptible input lag. Namely, in a combination of
dropped/missed inputs and delayed response to inputs the game receives.

This seems to be reproducible 100% of the time based on my experience and
generally everyone else I've asked, or read comments on the topic.

This input lag is so bad it means World of Warcraft should not be played on any
version higher than WINE 4.16 until this input lag bug is fixed, as it makes
gameplay elements (complex boss fights) nearly impossible.
