Looking over/grepping the code, Wine seems to ignore the CDS_FULLSCREEN flag. It *uses* it from within its d3d implementation, but the receiving code in winex11drv.dll doesn't pay any attention to this flag.
A well behaved application should react to loss of focus by restoring the desktop display mode, by calling ChangeDisplaySettings(NULL,0), and it should do the same at termination.
However, when an application switches the display mode using the CDS_FULLSCREEN flag, Windows itself will restore the desktop display mode when the application terminates. This makes it possible for applications that don't really abide by the rules to slip by on real Windows systems, but exhibit this issue on Wine.

I don't know whether your specific games fall into this category, or if there are maybe some other issues at work, but I'm quite sure that Wine's ignoring of the CDS_FULLSCREEN flag is at least a possible cause for the symptoms you're seeing.
