Description Carlos Garnacho Parro 2012-01-25 13:07:30 UTC 
With XInput >= 2.1, the valuators with a matching XIScrollClassInfo report absolute values in events, so if you scroll down you get say 1000, and if you scroll then up a bit you get 900.

To my understanding, these valuators should provide actual deltas, instead of leaving delta calculation up to clients
Comment 1 Peter Hutterer 2012-03-07 21:53:02 UTC 
no, we actually have to provide absolute valuators since XI doesn't allow us to report relative values in valuators. This is basically the reason for RawEvents.

_might_ be possible to tack on for XI 2.3 but don't wager your bets on it.

Mass closure: This bug has been untouched for more than six years, and is not
obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases.
