Bug ID: 35294
           Summary: Window borders shown over other windows
           Product: Wine
           Version: 1.7.9
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

Created attachment 47074
  --> http://bugs.winehq.org/attachment.cgi?id=47074
Opened Line window on top

Workflow: open a Line (http://line.naver.jp/en/) chat window. (window.png
attachment)
Switch to another window, so that the line window moves back.
Line window borders will remain visible(borders.png attachment: watch were
there was the window in window.png, you will see the borders)

I'm also unable to minimize the window, the button does nothing. The bug is
reproducible with "Allow window manager to manage the windows" checked; if I
uncheck it before launching wine, simply Line window stays over all other
windows (you will stay in the situation of window.png also if you focus another
window).

Running cinnamon on Arch Linux.
