Bug ID: 56009 Summary: Updating a wine prefix sometimes fails with X errors echoed in console. Product: Wine Version: 9.0-rc1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: hibbsncc1701@gmail.com Distribution: ---
The current wine-9.0 RC can sometimes fail to update a wine prefix. Generating X11 errors in the console, and aborting the prefix update process. The underlying problem seems to be a race condition, as it doesn't occur on every prefix update, and it seems to happen at different points in the update process when it does. It also seems more likely to occur when wine is emulating a virtual desktop. But I don't have hard numbers to confirm this.
Depending on when this bug happens in the prefix update running wineboot -u might fix it, but there is a small chance that the prefix will be corrupted beyond wine's ability to fix. Necessitating the creation of a new prefix.
