             Bug #: 30814
           Summary: Age of Empires II scrolling gets stuck after Alt-Tab
                    away and back
           Product: Wine
           Version: 1.5.5
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: nemesis at icequake.net
    Classification: Unclassified


Wine 1.2 did not have this problem but was much slower.
Wine 1.5.5 is much faster and just a much better overall experience with this
one caveat.

If you start a game and immediately alt-tab away and back, nothing is amiss. 
You can even click on some things onscreen and there is no problem.

However, once you have scrolled the screen either by moving the mouse towards
the edges, or by using the arrow keys on the keyboard, if you alt-tab away and
back, upon returning the screen will immediately begin to scroll in an
apparently random direction and cannot be stopped.

I did the WINEDEBUG="+cursor,+dinput,+ddraw" winedbg Age2_x1/age2_x1.exe and
did not come up with anything obviously wrong while the problem was occurring. 
A lot of this kind of stuff:
