The issue is twinview give me a 3360x1050 screen resolution. I want Eve to run fullscreen on a single display (1680x1050). Forcing xinerama interfer with nvidia implementation and award me with many issues : gnome bar don't stretch, h/w issues . . . Using compiz allow me to 'fix' nvidia binary drivers misbehaviour on dual display. But it seems newer versions of wine had some fixes/issues regarding window handling. Anyway, on long term i'll have to switch to newer gnome desktop & drop compiz, so the whole problem remain.
