Public bug reported:
**Package:** easyeffects 8.1.2+ds-1
**Release:** Ubuntu 26.04 LTS (resolute), Qt 6.10.2, GNOME/Wayland
## Summary
All icon-only controls in Easy Effects render as blank/invisible squares
because nothing in the dependency chain installs `qt6-svg-plugins`. Every icon
in the app (Kirigami/qqc2-desktop-style, breeze icon theme) is an SVG;
`libqt6svg6` ships only the library, while the QSvg imageformat and iconengine
plugins (`imageformats/libqsvg.so`, `iconengines/libqsvgicon.so`) live in
`qt6-svg-plugins`, which is not pulled in by easyeffects,
qml6-module-org-kde-kirigami,
or qml6-module-org-kde-desktop.
## Impact
On a system without a Qt/KDE desktop (e.g. stock Ubuntu GNOME), the per-effect
enable (power) toggle, remove buttons, drag handles, EQ band menu buttons and
all toolbar icons are invisible — controls exist but show nothing until
hovered. Users cannot tell their effects are bypassed or how to enable them.
KDE installs mask the bug because something else in a Plasma install drags the
plugins in.
## Steps to reproduce
1. Minimal Ubuntu 26.04 GNOME install; `apt install easyeffects` (verify
`qt6-svg-plugins` is not installed).
2. Launch easyeffects, add an Equalizer effect.
3. Sidebar effect rows show no visible toggle/remove controls; icon buttons
throughout the UI are empty squares.
## Expected
Icons render. Installing `qt6-svg-plugins` (or pre-loading its plugins via
`QT_PLUGIN_PATH` from the extracted deb, which was used to bisect this)
immediately fixes every missing icon.
## Suggested fix
Add `Depends: qt6-svg-plugins` — arguably at the right layer:
`qml6-module-org-kde-kirigami` (or qml6-module-org-kde-desktop), since any
Kirigami app is unusable without SVG icon rendering; easyeffects should at
minimum Recommend it. dh_shlibdeps cannot detect runtime-loaded plugins, which
is how this was missed.
## Workaround
`sudo apt install qt6-svg-plugins`
