Summary: mcm2: graphical glitches and extreme lag while in menu
           Product: Wine
           Version: 1.1.14
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Both the demo and the retail version of Motocross Madness 2 suffer from an
extreme lag in mouse movement while in the application's menu. The screen
reacts as if there were only one refresh every two seconds.  The mouse is
jerky.  OTOH, during game play, FPS and responsiveness seem normal (from what I
can tell from just a little testing).

The menu graphics are mostly correct, with these anomalities:

- There is no refresh, i.e. if anoyther window shadows part of it, the region
becomes black.  More precisely, when the mouse if moved over those black areas,
a tiny rectangle the size of the mouse pointer is restored.  Clickable icons
are restored in full as the mouse hovers over them.

- Each time the mouse passes over one of the buttons in the main menu (with the
chains), the whole background screen darkens. I don't know whether this is
normal for lack of comparison with MS-Windows.  However, the mouse moving over
the background restores it to the original, lighter tune.

- More precisely, mouse movement is fine in the menu until it passes over one
clickable area. Then it stops for a second. After that, the button and tooltip
appear highlighted / refreshed.
Switching from one menu to another causes like a 5 second lag until the mouse
moves again, even though the new screen is displayed somewhat earlier.

- In Ubuntu Hardy, unlike Intrepid, there are major graphical glitches in the
display (see screenshot): More and more black horizontal lines cover the
display each time the mouse moves over one of these buttons. (With wine-1.0.1
colored vertical lines are randomly displayed instead).
In Ubuntu Intrepid, this does not happen.
Hmm, might be gone since 1.1.14, I just saw only a single erroneous line today.

- The application manages to limit the mouse to its window even though my
setting in winecfg ought to disable this behaviour.
fixme:dinput:SysMouseAImpl_Acquire Clipping cursor to (0,0)-(112,27)
is the logline accompanying this behaviour (which some other applications also
exhibit). Using Alt-Tab *and* wild mouse movements it typically can escape.
