Bug ID: 57530
           Summary: Regression: Tiny extra form displays in Delphi
                    programs
           Product: Wine
           Version: 9.22
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

This is a regression that began in version 9.22. In winecfg, verify that both
'Allow the window manager to decorate the windows' and 'Allow  the window
manager to control the Windows' are enabled. Beginning with version 9.22,
Delphi programs will display an extraneous 1x1 pixel form in the exact center
of the screen. If the window manager is allowed to decorate the Windows, then
it will add a tiny frame and title bar to this one pixel. This can be tested by
using Inno Setup (https://jrsoftware.org/isdl.php) or any program that uses
Inno Setup to install itself.
