Bug ID: 45633
           Summary: Fallback to /tmp if /run/user/_uid_ is not accessible
           Product: Wine
           Version: 3.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

I'm noticing that Wine uses now /run/user/_uid_ instead of /tmp for temporary
files but in some cases /run/user/_uid_ might not be accessible for example if
systemd-logind is not running (it also appears there is no option to choose the
temporary directory to easily workaround this). Wine could try to fallback to
/tmp in such cases to continue working.
