Bug ID: 519981
Summary: Hunyango wallpaper does not update accentColor as its
color cycles, leaving "Accent color from wallpaper"
stale
Classification: Plasma
Product: plasmashell
Version First 6.6.4
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Hunyango wallpaper
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
The Hunyango wallpaper plugin (kdeplasma-addons → wallpapers/hunyango)
animates a background Rectangle through a continuous loop of randomly
generated HSL colors via ColorProvider.qml (a 30s color animation
followed by ScriptAction triggering the next color, repeating forever).
When the user enables Settings > Colors and Themes > Colors >
"Accent color from wallpaper", the accent color is computed once
(presumably from the SVG / initial state) and never updates as
Hunyango cycles. Result: the accent stays frozen at one color while
the visible wallpaper background continuously changes through the
full hue spectrum, creating obvious mismatch between the wallpaper
and the rest of the UI tinting.
Inspecting the source confirms the cause:
/usr/share/plasma/wallpapers/org.kde.hunyango/contents/ui/main.qml
/usr/share/plasma/wallpapers/org.kde.hunyango/contents/ui/ColorProvider.qml
Hunyango never assigns to wallpaperInterface.accentColor. By contrast,
the org.kde.image wallpaper does so explicitly in
ImageStackView.qml:117-120 (`wallpaperInterface.accentColor =
mediaProxy.customColor`),
which is why "Accent color from wallpaper" works for static images.
Bug 487572 ("Accent color from wallpaper doesn't sync with new
Picture of the Day", RESOLVED FIXED in 6.4) addressed the same
class of issue specifically for the POTD plugin. The same fix
pattern needs to be applied to Hunyango.
Steps to reproduce
------------------
1. System Settings > Colors and Themes > Colors > set "Accent color
from wallpaper".
2. System Settings > Wallpaper > select "Hunyango".
3. Apply, observe initial accent color (e.g. taskbar highlights, focus
rings, switches).
4. Wait 30 seconds — the wallpaper background visibly transitions
to a new random hue.
5. Observe accent color: unchanged.
6. Wait several minutes — wallpaper has cycled through many hues,
accent still unchanged.
Actual result
-------------
Accent color is computed once at wallpaper load and never updates,
even though the visible background is continuously changing.
Expected result
---------------
Accent color tracks the current wallpaper background color (or a
derived value from it), updating as Hunyango cycles. A small lag
is acceptable; complete absence of updates is not.
Suggested fix
-------------
In wallpapers/hunyango/contents/ui/main.qml, expose the current
ColorProvider.color to the wallpaper interface, e.g.:
Connections {
target: ColorProvider
function onColorChanged() {
wallpaperInterface.accentColor = ColorProvider.color
}
}
(Or equivalent on the Rectangle, or by binding
`wallpaperInterface.accentColor: ColorProvider.color` directly.)
Note: the Haenau wallpaper has the same issue (no accentColor
assignment), though there it is less visible because the visible
color is more constant. Worth fixing both in the same MR.
