To work around this Wine should detect desktop change and block system "minimize" message. Instead it should hide a window some other way and restore it when desktop is switched back.
I am not sure, but I think that when you switch desktop window manager moves whindows out of the screen , and not minimize them. I wine x11 driver that minimizes windows in this case.
