So the problem is that it's giving aome paths that plasma is not familiar with: ({'Id': <'steam'>, 'Category': <'ApplicationStatus'>, 'Status': <'Active'>, 'IconName': <'steam_tray_mono'>, 'IconAccessibleDesc': <''>, 'AttentionIconName': <''>, 'AttentionAccessibleDesc': <''>, 'Title': <'Steam'>, 'IconThemePath': <'/home/apol/.local/share/Steam/public'>, 'Menu': <objectpath '/org/ayatana/NotificationItem/steam/Menu'>, 'XAyatanaLabel': <''>, 'XAyatanaLabelGuide': <''>, 'XAyatanaOrderingIndex': <uint32 0>},) The file is instead in: ~/.var/app/com.valvesoftware.Steam/.local/share/Steam/public/steam_tray_mono.png It could make sense to see if the process is coming from flatpak and in these cases translating the paths.
