Bug #: 34796
           Summary: Flickery mouse cursor in Age of Empires II
           Product: Wine
           Version: 1.7.4
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

I was using Age of Empires II in Wine 1.4.1 from Debian packages, and it worked
fine in general. I upgraded to Wine 1.7.4, and the mouse cursor is now
flickery, choppy, and sometimes jumps around randomly, making the game quite
annoying to play. Other aspects of the game seem to have lower framerate too,
but this is more subtle and I may be imagining things; the mouse cursor issue
is definitely the most noticeable.

I also got some crashes, but they are rare, random, and hard to reproduce.

I ran a full git bisect between 1.4.1 and 1.7.4 (which took me quite a while),
and identified 3c023a5db5538a7622d4518e8ce24d36e1c459b1 as the commit
introducing this regression ("wined3d: Just set the first render target to NULL
in wined3d_device_reset()"). The mouse cursor movement is absolutely smooth
right before that change.
