           Summary: Mouse input causes major performance loss
           Product: Wine
           Version: 1.3.28
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: pastas4 at gmail.com


Since I upgraded from Wine 1.3.26 to 1.3.28, I have noticed a regression in all
games I have installed on Wine - their performance is a lot lower and in some
of them graphical glitches appear.

The performance regression is clearly due to the input. For example, if I don't
move the cursor, everything works fine - the performance is what it was earlier
and there are no glitches, but as soon as I move the mouse, the performance is
lowered dramatically (to around 1 FPS in every game I tested) and in some
cases, such as running Heroes of Might and Magic III in a virtual desktop,
graphical glitches appear (a box around the cursor that displays incorrect data
- from another part of the screen).
