--- Comment #1 from perfeitor <quanghuy19062...@gmail.com> --- (In reply to perfeitor from comment #0) After a few restarts, the error is gone, now I can receive notifications normally when minimizing the application with tray. This time when starting the application, whether it is minimized to tray or not, there will be 3 more processes than the last time I encountered the error: 1 dbus and 2 console -- You are receiving this mail because: You are watching all bug changes.
