wine users - May 2012 - How to fully return X11 after fullscreen Wine game exits?

I know this isn't technically a Wine problem or question, but I'm hoping
someone else who uses wine on Mac OS X has already figured this out.

I just got Blades of Time and figured I'd try it out on Wine on Mac OS X to
see if it works.  Lo and behold, it works just fine on Wine 1.5.3 with
raw3.patch.

The game changes the X screen resolution using xrandr, but when the game exits,
it leaves the X server at the same resolution with the background completely
black.

I issue a "xrandr -s 0" and the XQuartz returns to the correct native
resolution.  However, the black background is still there blocking my view of my
desktop.  I don't know if that's the root window or something else.  I
have to quit XQuartz to make the black background go away.

Does anyone know how to get rid of that black background after returning X to
the correct native resolution?

Thanks in advance.

CMD + Q, followed by "Enter" should help you

have you updated XQuartz lately?

to get the rootless window back you its not going to be -s 0 usually... you need
to look through the xrandr list, but its going to be a resolution with the right
X, but the Y will be 22 less than your actual Y.  Say your screen is 1920x1200,
the rootless resolution you want to switch back to will be 1920x1178... any
other resolution and you have a black shielding window.
