I don't have any reproduction steps, it was out-of-the blue as I was playing with weston-editor. However, weston itself came crashing down Thanks for filing a new report. Without steps to reproduce or a Valgrind error report, it's going to be hard to look into this, I guess. My first wild guesses would be either a stale pointer to a weston_surface(?), maybe together with use-after-free, or a generic overwriting of unintended memory. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
