Bug ID: 38420
           Summary: Sticky mouse with xinput2
           Product: Wine
           Version: 1.7.39
          Hardware: x86
                OS: Linux

Hi, the Stalker series and also Sniper Elite have been affected by this issue
for years, since the infamous Wine "mousewarp" bugs.

When wine (currently tried upto 1.7.39) is *not* compiled with the option:

--without-xinput2

Then the full-screen mouse has a strange intermittent sticky/slowdown effect,
on both horizontal and vertical axes. It seems like xinput2's pointer barriers
are taking effect - the mouse gets some invisible resistance, and has to be
"pushed through" the barrier with extra force.

This is only an issue when wine is compiled *with* xinput2.

This is especially a problem with the Stalker games (e.g. Stalker Lost Alpha),
which need the mouse to work in the menu & inventory screens, as well as
first-person view.
