Thanks for checking that, Jactry, this is super helpful. Given it doesn't
happen in the Mac driver, I'm now convinced this is related to the X11 driver
and how it sets override redirection on only the border window.

I saw Alexandre's suggestion in #4 to disallow the window manager to control
the windows in winecfg, so I gave that a try. Of course this causes LINE to
stay above all other windows when configured this way. I checked the states of
both the content window and the border window in this state and both of them
have override redirection enabled (expected because this is the standard way to
ignore the WM).

Wine should not be overriding redirection on the border window. Fixing that
will at least solve the problem for managed mode but probably won't fix the
thick borders issue though.
