SUMMARY
After upgrading to Plasma/X11 5.21.5 I've noticed that title of Audacious
player on taskbar doesn't update when next audio file is playing.
STEPS TO REPRODUCE
1. Use Audacious with Qt5 classic winamp-like interface. Tested this with
Audacious 4.1.
2. Ensure there are only 2 windows of Audacious are present: main window and
playlist window.
3. Start playing audio file in Audacious. If it's first song, title of
Audacious might be updated to reflect name of audio file.
4. Make Audacious play another audio file or pause/stop playing. Any way is
fine: using 'next track', 'previous track', 'pause' or 'stop' buttons, clicking
on another audio file in playlist or just waiting until current audio file is
finished and next one is started.
OBSERVED RESULT
Title of Audacious on task panel doesn't update.
EXPECTED RESULT
Title of Audacious on task panel should update to reflect name of current track
or state of playback.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Plasma/X11
(available in About System)
KDE Plasma Version: 5.21.5
KDE Frameworks Version: 5.82.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
It worked fine with KDE Plasma 5.20.5. Downgrading fixes this issue for me.
Attaching screenshot with Audacious and part of tasks panel. Name of audio file
in main window and playlist window doesn't match name of audio file on tasks
panel in the bottom of screenshot.
Running "xprop" on main Audacious window shows correct window name. When
switching to different window via "alt+tab" key combination, correct window
name is displayed in task manager.
If Audacious has only one window, i.e. there is main window and no playlist
window, it updates name fine.
