STEPS TO REPRODUCE 1. Boot the system and/or 2. Launch an application which adds a system tray icon 3. OBSERVED RESULT The icon does not show, but is there and it could be interacted fine. EXPECTED RESULT THe icon would show properly. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Manjaro Linux KDE Plasma Version: 5.18.4 KDE Frameworks Version: 5.69.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION
I am unable to reproduce this bug on Arch Linux - icons like KeePassXC show up in the system tray as expected. Are you using third-party docks or widgets?
Can you also enumerate which non-kde applications specifically do not work for you?
A clarification over the report. First, it happens only at boot and not all the times, in case the bug happens, every application launched afterwise is affected. In case the bug is not triggered at boot, everything works fine. The application I had in the systray when the bug was triggered were a bunch of Electron applications (Discord, Skype, Slack, Telegram), Dropbox, and the Fcitx input method selector. Plasmoids such as the notification, media player, clipboard always show.
