Bug ID: 46836
           Summary: Battle.Net UI freezes when downloading big games after
                    a period of time
           Product: Wine
           Version: 4.3
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Best way to reproduce it:
1. Install Battle.Net and arial font using winetricks
2. Log in and start installation of some big game, for example, WoW (has a free
trial)
After some time (for me it was 10-15 minutes) the UI becomes frozen (nothing
moves) and completely unresponsive. However, it seems to still continue working
and downloading things, and restarting it helps to resolve it.
When this happens, I don't seem anything standout-ish pop in the terminal log.
Attached a log with during recording of which the bug occured.
