The main window shadow also can reproduce it.

You may need a account to login it and here is a account for testing:
account: [e-mail]
password: winehq

You can click the last button in the login window  (as pciture 3.png)  and
login it with this account.

Here is a hack for it.
This bug also impacts WeChat PC. It seems they use a same third party UI
library(ANGLE - Almost Native Graphics Layer Engine?).

Still affectes WeChat as of wine-4.3. The hack doesn't help. To reproduce:

https://mirrors.ustc.edu.cn/deepin//pool/non-free/d/deepin.com.wechat/deepin...

Extract the deb, then "opt/deepinwine/apps/Deepin-WeChat/files.7z", then run
"drive_c/Program Files/Tencent/WeChat/WeChat.exe"

With wine 4.16 & 4.19 I don't have this issue with WeChat but with 4.20 it's
back. I'll do a bisect later.

I find that these gray shadows are actually a window. They are supposed to
appear with the main windows but not aware of multiple desktops of X Window and
appear on every desktop. With WeChat I also have a small info window noting
about new messages 「↟X条新消息 | x」 appear on every desktop when it's shown.

I can use xwininfo to get the id of the shadow window and use xdotool
windowunmap wid to make them disappear (but they'll reappear when I minimize
and restore the WeChat window).

The patch doesn't work well for me with wechat. There is no longer shadows
shown on every desktop, but there is an unresponsive window covering wechat
windows.

I can manually move away the unresponsive window and use the window underneath,
but I can't get rid of it. The unresponsive window appears above the login
window, the chat window and the right-click menu of the tray icon.

I also experience this with PDF-Xchange Editor Plus version 9.3 on

KDE Frameworks Version: 5.76.0
Qt Version: 5.12.7
Kernel Version: 5.3.18-150300.59.68-default.
It's sufficiently annoying that I fall back to an older version of the
PDF-Xchange program which doesn't exhibit this characteristic.  A trial version
of PDF-Xchange can be downloaded from
https://www.tracker-software.com/product/downloads in case anyone wants to
check for themselves.

I found a workaround for this problem: Set the Windows Version to 10 in $
winecfg.

Drop shadow is still appearing for me, on top of all windows.
I run Wine 7.16 Staging, and see the issue for WeChat, DingDing, and their
installers. winecfg Windows 10 workaround does not work for me.

I've found a workaround in my instance of this bug. If I use an Ubuntu keyboard
shortcut to minimize the application window showing the drop shadow problem,
then the drop shadow no longer lingers on top of all windows even after the
main window is restored.

After starting the application fresh, if I use the minimize button that comes
with the application window, the drop shadow is gone. But the drop shadow will
come back when the main window is restored. If I use the keyboard shortcut,
then the drop shadow never comes back, regardless of how I restore / minimize /
resize the same window afterward. New windows created by the same application
may still show the drop shadow. Not all windows respond to the Ubuntu shortcut,
which is kind of annoying, but having the main window be responsive to that is
already a nice improvement.

This leaves me with a couple questions: if the drop shadow is behaving like a
window, why doesn't it appear as a separate entry in the dock like other cases
when an application has multiple windows, and why does the keyboard shortcut
handle this differently from pressing the minimize button?

I'm sure "the drop shadow" is a window,For DingTalk's drop shadow

———————————————

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

———————————————

so I think it's a window

I also saw your post on Bug 53771, good investigative work.

I think because of these options, the transparent window doesn't show up on the
dock / taskbar?
WS_EX_TRANSPARENT WS_EX_TOOLWINDOW WS_EX_LAYERED WS_EX_NOACTIVATE

My guess is that the Ubuntu shortcut minimizes all windows attached to the main
one, including tool windows, whereas the minimize button is actually just a
normal button on the window that doesn't minimize the transparent part. Perhaps
the restore logic doesn't explicitly restore the transparent window because
Wechat / QQ / DingTalk expects the transparent window to always be present.

Sven, does your tool show whether windows are truly minimized or not? If so
could you check if the transparent window is still there if you minimize
DingTalk on Windows?

I noticed that Ubuntu itself also draws drop shadows on windows that have
focus. But I verified that the shadow that lingers after minimization the app's
custom shadow, not Ubuntu's. For one, Ubuntu only draws the shadow on windows
that have focus. Secondly, the shadow looks different. See my attachments:

shadows_1 shows the Ubuntu drop shadow around a Firefox window that has focus
vs. a lingering buggy shadow from DingTalk vs. a shadow from a non-minimized
Wechat window that is not in focus. The Firefox shadow is lighter.

shadows_2 shows what I see if I give focus to the Wechat window. The Wechat
shadow is darker than even the buggy shadow from DingTalk, and there's no
shadow around the Firefox window. This means the Wechat window in focus has
both the Ubuntu shadow and the transparent window's shadow.

These results mean that the invisible shadow window is not minimized and still
rendering the shadow, as expected. What I don't know is what is supposed to
happen on real Windows - does the invisible window get minimized too, or does
the invisible window stay non-minimized and simply stops rendering the shadow?

The system I use is Debian+X11, in wine7.18, in fact when I click the shrink
button in the upper right corner of the window, the transparent window will
shrink synchronously.

I think the tool can't do this. The tool is WinSpy.exe you can download on

I found that the reason for the problem is that the window is not added to the
window manager, do you know which developer should discuss this problem with?

I would like to ask what is the reason for judging whether a window is added to
the window manager in wine. For example, in the is_window_manger function of
winex11.drv, I see that the child window in wine does not need to be added to
the window manager, and the full-screen window needs to be added to the window
manager.

====================

I would like to ask what is the basis for judging whether a window is added to
the window manager? I'm not asking the code logic for the judging in wine, I'm
asking why the code be coding like that? If we judging a window need to be add
to the window manager,What is the basis we follow？

such as : We know that the child window is managed by its parent window, so
there is no need to join the window management.

====================

Because I think a visible POPUP window (WS_VISIBLE) in the screen should be
added to the window pipe, but I want to know "the basis for judging whether a
window is added to the window pipe", and then judge whether my logic is
correct.

If my logic is correct then this bug will be fixed.

I refuted myself, adding the shadow window to the window manager can indeed
solve the problem, and the shadow window will not be displayed on the top
layer, but such modification will cause new problems, so there should be a
corresponding reason that wine did not do this in the design. consideration
(although I still don't know what kind of consideration)

I will still be here for getting the basis for judging whether a window is
added   to the window manager.

In my case i go to wine config > graphics >

"Allow the window manager to decorate the windows"
and it work for me.

With the Wayland driver enabled, this issue leads to WeChat and similar
applications being completely unusable.

With Wine 8.17 I was able to cycle the wine theme via winecfg between light and
dark to cause the shadow window to become visible.

As of Wine 8.19 I am no longer able to do the above bypass.

If DingTalk, WeChat, and other shadow-windowed applications are run via
wayland, all UI elements are completely inaccessible.

This sounds like an issue of the wayland driver.

Hardly, this specifically is an application issue.

These programs expect to be able to shadow a window on Windows.
X11 had support for this use case.

Wayland does not support this use case. It is quite impossible for Wayland to
ever support this use case, and it likely never will be supported.

Thus the only options are.

1. The developers of the application fix the issue by allowing the shadow to be
disabled.
2. Wine to explicitly deny the application the ability to do a shadow.

We have control over the second option. Thus should advocate for the second
option. Which is known to solve the issue.
