[Bug 21524] New: Mouse cursor is visible when Geiss goes fullscreen, but should be invisible

http://bugs.winehq.org/show_bug.cgi?id=21524

Summary: Mouse cursor is visible when Geiss goes fullscreen,
                    but should be invisible
           Product: Wine
           Version: 1.1.37
          Platform: x86-64
               URL: http://www.geisswerks.com/geiss/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

1. Install foobar2000: http://www.foobar2000.org/
2. Install Geiss, a visualisation plugin for Winamp:
http://www.geisswerks.com/geiss/
3. Install Shpeck, a plugin for foobar2000 which allows it to use with Winamp's
visualisation plugins: http://www.foobar2000.org/components/view/foo_vis_shpeck

I'm using:
foobar2000 1.0
Geiss 4.29
Shpeck 0.3.7

In foobar2000, Preferences / General / Keyboard Shortcuts, I set up
Ctrl-Shift-K with the action: View / Visualizations / Shpeck - Start 'Geiss for
Winamp / Geiss for Winamp'. Next, I start an mp3 file, move the mouse cursor to
the top-left corner of the screen and press Ctrl-Shift-K. The Geiss plugin
starts successfully. The problem is that the mouse cursor remains visible, even
though Geiss is trying to draw on the whole screen. Moving the mouse has no
effect on the cursor at this point, it remains in the same position. The mouse
cursor should become invisible when the plugin is started.

Details: My normal screen resolution is X/Y. I set Geiss to use a lower screen
resolution, (X/2)/(Y/2). If I start Geiss when the mouse cursor is outside the
top-left quarter of the screen, the mouse cursor does not show up in Geiss.

The same happens when starting Geiss from Winamp.
