            Bug ID: 50299
           Summary: Application tried to create a window, but no driver
                    could be loaded.
           Product: Wine
           Version: 5.22
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown

0050:err:winediag:nodrv_CreateWindow Application tried to create a window, but
no driver could be loaded.

Running e.g. "wine notepad" in a quite slow environment for example within
rr-debugger inside a VM leads to the above message.

As far as I could follow in above line 0050 is "explorer.exe".
Unfotunately winemenubuilder.exe was a little bit earlier with requesting
the first window in WIN_CreateWindowEx
before explorer.exe reached manage_desktop.
Therefore explorer.exe never SetPropW("__wine_display_device_guid")
in DesktopWndProc.

This race might not show up under normal conditions, but I thought to
document it here to be findable.

Making winemenubuilder.exe sleep some time in wWinMain before CoInitialize
works around it.
