Volume slider

SUMMARY
When an application is playing audio, one can hover over the plasmashell app icon to see the preview + volume slider.

This volume slider does not appear for me when trying to run Steam over flatpak, but native Steam shows it just fine. Tested by playing a video in a store page.

STEPS TO REPRODUCE
1. Open Steam
2. Navigate to a store page
3. Play a video
4. Hover over the app icon in the task bar

OBSERVED RESULT
Volume slider on native, but not on Flatpak

EXPECTED RESULT
Volume slider in both cases

This is likely something specific to the Steam flatpak. I just tested, and I get a volume slider with the Haruna flatpak. If you test with that, you can determine if it's related to your system or the Steam flatpak specifically.

I presume you meant org.kde.haruna and not com.georgefb.haruna.

Haruna works, so does Telegram desktop, both on Flatpak.

Moving to the Task Manager component

I'm not able to reproduce this on Plasma 6.3.3. I have FreeTube installed from flatpak. When I hover the mouse over its icon in the task manager, I see a volume slider.

Do you see this bug with any flatpak other than Steam?

Comment 6 Martin 2025-04-04 22:26:54 UTC

Nope, so far only Steam.

Comment 7 Nate Graham 2025-04-08 16:32:09 UTC

I'd recommend reporting to Flathub and seeing what they say.
