            Bug ID: 36873
           Summary: Chronology (.NET 4.0 game) based on 'OpenTK': mouse
                    input non-functional, mouse cursor invisible
           Product: Wine
           Version: 1.7.21
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown

Hello folks,

the GOG.com version installs .NET Framework 4.0 client profile on its own in
clean 32-bit WINEPREFIX (without Mono).

If the mouse is moved (either in fullscreen or virtual desktop mode), the
console is spammed with:

That noisy stub (although annoying) doesn't seem to be the problem here.

See here for discussion and how it's implemented in 'OpenTK':

wParam, IntPtr lParam)

                    (short)((uint)lParam.ToInt32() & 0x0000FFFF),
                    (short)(((uint)lParam.ToInt32() & 0xFFFF0000) >> 16));

                // GetMouseMovePointsEx works with screen coordinates
                Point screenPoint = point;
                Functions.ClientToScreen(handle, ref screenPoint);
                int timestamp = Functions.GetMessageTime();

                };

                // Max points GetMouseMovePointsEx can return is 64.
                const int numPoints = 64;
                MouseMovePoint* movePoints = stackalloc
MouseMovePoint[numPoints];

                // GetMouseMovePointsEx fills in movePoints so that the most
                // recent events are at low indices in the array.
                int points = Functions.GetMouseMovePointsEx(
                    (uint)MouseMovePoint.SizeInBytes,
                    &movePoint, movePoints, numPoints,
                    Constants.GMMP_USE_DISPLAY_POINTS);

                int lastError = Marshal.GetLastWin32Error();

                // No points returned or search point not found
                if (points == 0 || (points == -1 && lastError ==
Constants.ERROR_POINT_NOT_FOUND))
                {
                    // Just use the mouse move position
                    OnMouseMove(point.X, point.Y);
                }
                else if (points == -1)
                {
                    throw new System.ComponentModel.Win32Exception(lastError);
                }
                else
                {
...
--- snip ---

That information might be still useful for 'GetMouseMovePointsEx'
implementation though.
