QWindowsWindow::setMouseGrabEnabled: Not setting mouse grab for invisible window

I just updated to Substance Designer 14.1.1.  Whenever I click on one of the menus at the top of the screen, a warning message is printed to the Console:

    QWindowsWindow::setMouseGrabEnabled: Not setting mouse grab for invisible window QWidgetWindow/'Pfx.Editor.Menu.FileWindow'

The name at the end of the message changes depending on which menu I'm clicking on.  For example, instead of "FileWindow", it might say "EditWindow" or "ToolsWindow".

The functionality of the various menus does not seem to be affected.  The only reason this is an issue is that we use custom scripts here and will sometimes direct the users to look at the console output.  For example, "Errors occurred while exporting textures.  See Console for details."  If the users see the "setMouseGrabEnabled" warning message, they may think it is part of the reason there was an error exporting textures.
