Bug ID: 44024
           Summary: Battle.net leaves processes open after exiting.
           Product: Wine-staging
           Version: 2.20
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

      Distribution: ---

When exiting the Blizzard App / Battle.net client, the application window
closes, but looking in system monitor shows that there is a Battle.net.exe and
an Agent.exe still running, as well as the associated wine processes such as
wineserver etc.

These persist until Battle.net.exe and Agent.exe are killed manually, in that
order.

If the application was launched in a virtual desktop, the desktop will remain
open and visible, but unusable.

This bug would perhaps affect plain wine as well as staging, but there are
other issues that prevent plain wine from running Battle.net.

Unable to find any workaround for this, except for manually killing the
processes in task manager.
