Summary: Running any Half-Life based game in "Windowed Mode"
                    corrupts mouse movement
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-dinput
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I have tried many steam games with this and many versions of Wine ranging from
0.9.48-1.1.4. For testing purposes try this with Counter-Strike Source.

To replicate:
1. Start Steam.
2. Edit parameters for Counter-Strike: -windowed
2.5 Also add any additional resolution parameters needed
3. Start Counter-Strike
4. Join server. When you spawn, or are spectating in freemode, the mouse will
automically and slowly start moving toward the top left.

To worsen this, if you move the Counter-Strike window to another location and
then go back to the game, the mouse will move at an even faster rate. This will
definately replicate it if it couldn't be replicated in the previous step.

This is reproducable every time. The in-game crosshair will always start moving
toward the top left.

NOTE: When you press escape (which takes you to the menus/etc) the mouse is
still. This problem only occurs in game when you are playing.
