It seems that outline is drawn on Root window and this patch creates only
window region for top leve X windows (child of root), so 1) occur.
I don't know how to solve it.

How about "CreateRectRgn (0, 0, 4, 4)" in winUpdateRgn(WindowPtr pWin)
instead of "CreateRectRgn (0, 0, 0, 0)"?
It makes small top left area of root window visible.

Sorry. I have not used x2x, and I have only one display, so I can't
