--- Comment #85 from Anton Vorobyov phoenix@mail.ru 2012-08-03 04:54:16 CDT --- I'm not using it. Please direct such matters to either corresponding bug (if possible, with regressing it to broken commit) or to general dota 2 discussion:

Also keep in mind that dota 2 / steam update could trigger it, not necessarily change in wine.
