More particularly, I see that the ShowWindow function in Wine first 
calls a user function and then sends the message (WM_WINE_SHOWWINDOW, 
cmd) to the window. Most apps don't seem to have a user function, so I 
guess the later message iconifies the window.

In the case of Xilinx, there is a user function that just does:

0806f758:Call window proc 0x5f401b81 

It is within this call that the X11DRV_ShowWindow() with a cmd==SW_HIDE 
is called, which in turn calls

      trace:win:SetWindowPos hwnd 10021, after 0, 0,0 (0x0), flags 00000097
     trace:win:dump_winpos_flags flags: SWP_NOSIZE SWP_NOMOVE 
     0806f758:Call x11drv.SetWindowPos(404863c8) ret=4077aa2e

Then all this returns and Wine sends the (WM_WINE_SHOWWINDOW, cmd) 
message, which does another SetWindowPos. So the SetWindowPos command is 
sent twice, though I haven't figured out whether that is the problem.
