Bug ID: 55161
           Summary: IrfanView full screen mode creates an unneeded and
                    uncalled for permanent overlaying panel
           Product: Wine
           Version: 8.6
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2

Panel

Steps to reproduce:

1) Download https://www.irfanview.info/files/iview460.zip
2) Run
3) Open any image
4) Press Enter or View -> Full screen
5) Press Enter once again (to leave full screen mode)

Result:

At this point at the bottom of the screen a 100px high permanent on top of the
screen panel will appear.

This panel must _not_ exist.

What's worse if you run any other Windows application in parallel and you exit
IrfanView, this panel will continue to be shown until wineserver exits.

This is a regression, sorry I cannot bisect at the moment.
