Bug ID: 53797
           Summary: Performance regression in Battle.net / Wow.exe using
                    wine-staging 7.18
           Product: Wine-staging
           Version: 7.18
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Using wine-staging 7.18-1 (Arch package) Battle.net application performance
appears degraded, with UI turning black and application freezing randomly.
Application is also completely frozen after system suspend and must be killed
from terminal.

Similarly, loading times in World Of Warcraft are severely degraded with the
game freezing for several seconds on first load and then very slow loading of
new Zone data.

Both symptoms appear to be resolved when downgrading back to wine-staging 7.17.
