http://bugs.winehq.org/show_bug.cgi?id=58305 Bug ID: 58305 Summary: Sonny (RPG game) randomly freezes during gameplay Product: Wine Version: 10.8 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wineserver Assignee: wine-bugs(a)winehq.org Reporter: doucha(a)swarmtech.cz Distribution: --- Sonny, a game on Unity engine, started randomly freezing during gameplay after I've updated WINE from v9.18 to v10.8. The game stops accepting input and even the audio stops playing. But if I move mouse out of the WINE virtual desktop and back in, the game starts working again. Here's what CPU usage looks like during normal play and frozen state: Normal: - SonnyWindows.exe: 37% CPU - wineserver: 8% CPU Frozen: - SonnyWindows.exe: 1% CPU - wineserver: 100% CPU I've managed to bisect the issue to the following commit: commit 87ca5db40e2c1b37423bdc25101a5c5e39e67e6f server: Use epoll_pwait2 for the main loop on Linux. If I comment out #define HAVE_EPOLL_PWAIT2 1 in config.h and recompile WINE, the problem goes away. Game link: https://armor-games-studios.itch.io/sonny I use Gentoo Linux. The issue may be reproducible in other Unity games as well. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
