Description Jeremy Linton 2025-06-07 15:46:42 UTC

I'm seeing random crashes running qemu/libvirt/etc stack in F42 and it appears to be fixed by:

https://gitlab.freedesktop.org/pixman/pixman/-/commit/106323bc15c7eb89a033cf8ff38f52bca8a4b53c

Which is part of pixman 46.0.

Either that patch needs to be backported or the version in F42 bumped.

Thanks,


Reproducible: Always

Steps to Reproduce:
1. use virt-manager with GUI/spice and eventually quemu will crash with backtraces that match the freedesktop issue linked above.
2.
3.
