Bug ID: 53771
           Summary: [QQ&WeChat&DingTalk] Window's edge decoration window
                    is always on top
           Product: Wine
           Version: 7.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major

My English is not good, so I hope to be forgiven if there are any poor
wordings.
Nowadays, many windows are composed of two windows (e.g. QQ, WeChat, DingTalk),
one window M is used to draw the user's interface, and one window S is used to
modify the previous window (e.g. edge shading, etc.).
 The following diagram is provided for a better understanding of this issue:

I found that when many windows' applications run on wine, the window used to
modify (window S) is always on top (even if it is covered by other linux
applications, the window S is always on top and does not disappear).This
affects the usage of the app.
I found this problem exists in wine7.12, know 7.18 also did not solve

Possible useful information for Window S(which is used to modify the previous
window)：
APPS：DingTalk
APP_Download_URL:https://dtapp-pub.dingtalk.com/dingtalk-desktop/win_downloader/dingtalk_down...
[ You can reproduce the problem without an account ]
- Function calls for drawing windows：CreateWindowExW -> WIN_CreateWindowEx
- Windows className:DuiShadowWnd
- style: WS_POPUP WS_CLIPSIBLINGS  style=84000000
- exstyle: WS_EX_TRANSPARENT WS_EX_TOOLWINDOW WS_EX_LAYERED WS_EX_NOACTIVATE
ex=080800a0

Because I'm not very familiar, I want to know what is the reason for this
phenomenon, I want to solve this problem through my own efforts, but I don't
have any good ideas now, so I come here and looking forward to your
suggestions.
