Ok I spent some time looking at the functions indicated by source files and line numbers from other threads, like that related to CoverArtCache, but you are right. Have yet to test with a build without PerfTools actually. Gotta be a bit later though. > we should create a new issue Will do. I was

The hang on exit while closing the sound devices is unrelated. Probably not a deadlock, only a slow I/O operation and hardware interaction. Hard to trace without the actual device setup at hand. Now we know that the deadlock is originating from WOverview. Do you still experience any deadlocks aft

Since this deadlock is probably not related to the original issue that has already been fixed we should create a new issue. Otherwise tracking becomes difficult. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.ne

I just had it hang when exiting the program, at a time of low CPU load. Curiously enough, attaching the debugger in order to obtain the backtrace was sufficient to make it recover (when I detached the debugger the program closed successfully). I know it sounds exotic but I'm actually documenting t

tcmalloc could even be faster than the system allocator. But as already mentioned this is not used in any of the official builds. Please first do a local build with the original Arch settings and try to reproduce the deadlock with a full stacktrace. Then rebuild without these options. -- You rec

Version 2.2.4 was tagged much earlier but then not released officially due to internal build server issues. Nothing to worry about. The issue might depend on the exact Qt version, the build settings used by Arch, and how Mixxx is started (i.e. with "-platform xcb" on Wayland?). I have never experi

I've been getting this on Mixxx 2.2.4 (which somehow was released to Arch Linux much sooner than the official release which was just yesterday) for the past 5 days or so.
