ProbeLabs65 findings · 95 requirementsA proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

Original report
System details
Intel i9-12900K, AMD Radeon RX 7900 XT/XTX (Navi 31), Omarchy 4.0.2-1
- Quickshell 0.3.1-1, Qt 6.11.2, Hyprland 0.56.2, PipeWire 1.6.8, WirePlumber 0.5.15, kernel 7.1.9-arch1-2
- Two 2560x1440 monitors at scale 1
What's wrong?
With several audio devices, the per-app mixer in the audio panel is pushed below the bottom of the panel. You only see the SOURCES header, with nothing under it and no sign that the panel scrolls, so it looks like the mixer is empty or broken.
I have 4 outputs and 4 inputs (USB interfaces, a monitor, a capture card). Together with the output and input sliders, that fills the whole panel. Chromium and mpv were both playing at the time: wpctl status listed both streams, and the SOURCES header only renders when displayAudioStreams.length > 0. The app rows were there, just clipped. Scrolling the mouse wheel inside the panel reveals them.
Steps to reproduce
- Have 4 or more output devices and 4 or more input devices connected.
- Play audio in one or more apps.
- Open the audio panel (click the bar icon, or Super+Ctrl+A).
Actual: The panel ends at the SOURCES header. No per-app rows and no scrollbar are visible.
Expected: The per-app sliders are visible, or it's obvious that more content is below.
Cause
The panel's content height is capped at Style.space(560), and the column sits in a ScrollView. The vertical scrollbar is AsNeeded, so it only appears while you're scrolling:

- https://github.com/omacom/omarchy/blob/quattro/shell/plugins/panels/audio/Panel.qml#L693
The per-app section is also the last one, so it's the first thing to be cut off. Both lines are the same on quattro as in 4.0.2.
Possible fixes
- Show the scrollbar whenever the content overflows, or add a fade/cue at the bottom edge.
- Collapse the output and input device lists to the selected device, and expand them on demand.
- Move the SOURCES section above the device lists, since apps are what you adjust most often.

#9538: once you do scroll down, the per-app sliders don't take mouse drags. That's a separate bug in StreamRow, and together the two make the per-app mixer hard to find and hard to use with the mouse.
Screenshot attached.
