I believe I have found a possible root cause for this. The game allows you to specify which monitor to display to, under System->Graphics->Monitor. On Windows, the choices are Primary/Monitor 1/Monitor 2. On Wine, only Primary/Monitor 1. The x11drv logs do show that Wine detects both monitors, but that information isn't getting relayed correctly to the game. I believe if that is fixed, then I would be able to select Monitor 2 (or it would detect it as the Primary).
In that case, could you try the following patch and see if it fix the issue for you?
