Tested with the GOG.com version but can also be reproduced in the original
demo.
The mouse pointer is working (buttons are clickable) it is just invisible.
Occurs in fullscreen and virtual desktop mode.

The problem is present since Wine-8.11 and the result of the regression test:

winex11: Set the window cursor immediately in SetCursor.

Instead of synchronizing the cursor on mouse changes. The SetCursor call
    should now only be made when cursor or window handle have changed.

Opening the demo shows a black screen with 2 empty rectangles: the left one is
starting the game.

Still present in wine-8.17-190-g8943fcbca49
