  fix: prune per-monitor windows on monitor removal (v0.6.15)

  nevaforget released this 2026-06-02 16:32:29 +02:00 | 7 commits to main since this release

  Resume-unlock SIGSEGV: connect_monitor only adds windows to all_handles,
  never removes them when a monitor powers off on suspend. gtk4-session-lock
  unmaps and drops its own ref, but the GtkApplication and all_handles keep
  theirs, so the orphaned window survives until unlock — where destroying it
  dereferences its now-NULL monitor association and crashes.

  Watch display.monitors() and prune handles whose monitor is no longer
  valid, releasing the app ref via remove_window (the lib already unmapped
  and dereffed the window — we must not destroy it ourselves).

  Revert the earlier idle_add_local_once deferral: the logs proved it
  ineffective (crash happens inside the idle trampoline). Diagnostic unlock
  logging kept until a suspend/resume cycle confirms the fix.
