Summary: open Steam window consume 100% cpu Product: Wine Version: 0.9.61. Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: dmiceman@ubiz.ru
Mostly (not always) open window of Steam.exe cause full processor load. When window closed to the tray — everything is fine. Sometimes, opening it again are ok too — processor is idle.
Seems to be a regression from a versions about 0.9.3x — as i can remember, there was no such problem with old versions (but of course, there was other problems with Steam).
