Bug ID: 518203
Summary: Hide Cursor effect missing despite config module and
metadata present
Classification: Plasma
Product: kwin
Version First 6.6.3
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: effects-various
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Summary
The "Hide Cursor" desktop effect appears to be partially present in Plasma
6.6.3, but is not functional or available as an effect.
The configuration module (kwin_hidecursor_config.so) is installed
The effect metadata (hidecursor.json) is present under builtin-effects
However, no runtime effect plugin is present or loadable
The effect is not listed by KWin and does not function
This results in a dangling UI/config entry without an associated backend
implementation.
Steps to Reproduce
Install Plasma 6.6.3 on Arch Linux (X11 session)
Check for effect plugin:
ls /usr/lib/qt6/plugins/kwin/effects/ | grep -i cursor
Query installed files:
pacman -Ql kwin | grep -i hidecursor
Query KWin for available effects:
qdbus org.kde.KWin /KWin org.kde.KWin.listOfEffects
Open System Settings → Desktop Effects and search for "Hide Cursor"
Actual Results
No kwin_effect_hidecursor.so (or equivalent) exists in
/usr/lib/qt6/plugins/kwin/effects/
Installed files include:
/usr/lib/qt6/plugins/kwin/effects/configs/kwin_hidecursor_config.so
/usr/share/kwin-wayland/builtin-effects/hidecursor.json
hidecursor does not appear in listOfEffects
Effect is not available in Desktop Effects UI
Cursor does not auto-hide during inactivity
Expected Results
One of the following should be true:
The effect is fully available and functional (listed, loadable, configurable),
or
The effect is fully removed, including:
config module
metadata
UI references
Current state suggests an incomplete removal or missing runtime implementation.
Additional Information
Plasma version:
plasmashell 6.6.3
KWin version:
kwin 6.6.3
Session: X11 (kwin_x11)
Fully updated system (pacman -Syu)
Reinstalling kwin does not restore any effect plugin
Notes
The presence of hidecursor.json under kwin-wayland/builtin-effects suggests the
effect may have been converted into a built-in effect. However:
It is not exposed via listOfEffects
It does not appear active
It is not configurable via UI
This may indicate:
a regression specific to X11 sessions, or
an incomplete transition from plugin → built-in effect
