Bug ID: 57679
           Summary: SimHub shows black window when the app is minimized.

          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv
          Assignee: [e-mail]

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.
