Summary: Steam games crash on startup if in-game community is not disabled Product: Wine Version: 1.1.40 Platform: x86 OS/Version: Linux Status: NEW Keywords: download Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: dank@kegel.com
(I looked, but couldn't find a bug for this, so here goes.)
Launching any game (say, Braid Demo) hangs quickly. To work around this, go to Settings > Friends > "Notifications and Sounds", uncheck all checkboxes, and select "Never" for "Flash Window". Then go to Settings > In-Game and uncheck the "Enable Steam Community In-Game" checkbox. The game should launch ok now.
