Bug ID: 41955
           Summary: Guild of Dungeoneering presents a black screen unless
                    using wine-staging
           Product: Wine
           Version: 1.9.24
          Hardware: x86-64
               URL: https://www.gog.com/game/guild_of_dungeoneering
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: Ubuntu

Guild of Dungeoneering is an Adobe AIR-based game which refuses to progress
beyond an empty black window on a fresh Wine 1.9.24 prefix and appears to
consume all idle CPU time while doing so. (But without fighting with other
applications to consume an entire core as is more common)

However, it will run perfectly under wine-staging 1.9.23 with CSMT enabled and,
with CSMT disabled, will scramble up the draw order, resulting in flickering
and invisible UI elements.

I've tested both 32-bit and 64-bit Wine prefixes and it appears to make no
difference aside from the 64-bit prefix adding a crash on exit.

I don't know which kinds of logs would be appropriate to attach in a situation
like this.
