Bug ID: 53609
           Summary: Segmentation fault when starting Dosbox.exe in virtual
                    desktop mode
           Product: Wine
           Version: 7.16
          Hardware: x86-64
               URL: https://sourceforge.net/projects/dosbox/files/dosbox/0

                OS: Linux
            Status: NEW
          Keywords: download, regression
          Severity: normal
          Priority: P2
         Component: win32u

   Regression SHA1: 0ad2db66a109b4c0a46d04ff8231706fff540941
      Distribution: ArchLinux

The problem started happening in Wine-7.16 affecting many apps/games on my
system.
E.g. when starting dosbox.exe in virtual desktop mode, the Dosbox logo is shown
for a moment then it quits. There is a 'Segmentation fault (core dumped)'
message in the terminal.
Starts properly in Wine's fullscreen mode.

Reverting commit 0ad2db66a109b4c0a46d04ff8231706fff540941 fixes the problem for
me.

To reproduce:
Download and install DOSBox0.74-3-win32-installer.exe then try to start
DOSBox.exe while virtual desktop is enabled in Wine.
