Bug ID: 57679
           Summary: SimHub shows black window when the app is minimized.
           Product: Wine
           Version: 10.0-rc2
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv
          Assignee: [e-mail]
          Reporter: [e-mail]
   Regression SHA1: 2e6820ee4ba30b1a8831d29937a369b9b548656b
      Distribution: ArchLinux

Usually this black window (rectangle) appears at the same place as the
minimized window. When the app window is maximized again, it covers the black
window. After several minimize/unminimize attempts, though, the black rectangle
will appear elsewhere on the screen. After that the main window unminimizes at
this new place, with its window controls (close box, minimize box, etc.)
unresponsive to mouse clicks.

SimHub (https://www.simhubdash.com) is a WPF app and requires .NET 4.8 to
function properly.

Here the app window is minimized once, where the black window appears exactly
on its place. Then the app window is unminimized to its original place covering
the black frame.

Then the app window is minimized again. This time the black frame is much
smaller and appears at the top left corner of the screen. When the app window
gets unminimized, it appears at the top left corner, with its window controls
unresponsive to mouse clicks.

This is taken with the commit preceding the regression -
10.0rc1.r17.a1e62217712

The app window minimizes/unminimizes without any problems.

Although this seems to have the issue with drop-down lists that 2e6820ee4ba
commit actually fixes.

Is this still happening with Wine 10.19?

It's better now.
The black window seems to be replaced by two floating windows with identical
coords, which are placed in the upper left corner of the screen. They are as
thin as a titlebar, without any controls on them, and quite small. When a game
starts, they appear on top of the game window. And can be closed with Alt+F4
without any issue for SimHub. On Windows these objects are not visible.
I'd assume this is part of the SimHub dash functionality, which places custom
dash overlays on top of the game screen. I don't use this functionality on
Wine, since it makes my GSync monitor run at max frequency all the time.

The part of this bug report about unresponsive controls after a while, seems to
have been fixed. It no longer appears.

There is another thing that is probably related to the part of the bug report
about unminimizing at a different (wrong) place on the screen.
Now the app always unminimizes at the center of the screen, regardless of where
the initial position was. This app minimizes/unminimizes to the system tray.

In the attached log, I made two attempts to minimize the main app window at
various places of the screen. Both times it unminimized at the center. I also
hovered/clicked on the floating windows, and then closed them with Alt+F4.
