Bug ID: 500098
Summary: Window Action Maximize/restore behaves weirdly when
using a touchpad since Plasma 6.3
Classification: Plasma
Product: kwin
Version: 6.3.0
Platform: NixOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-window-management
Assignee: kwin-bugs-n...@kde.org
Reporter: tamale-kooky-ni...@duck.com
Target Milestone: ---
SUMMARY
Since Plasma 6.3, the Window Action "Maximize/restore" behaves weirdly when
using a touchpad, especially when trying to maximize.
STEPS TO REPRODUCE
1. Use Wayland
2. Use a touchpad
3. Under Settings -> Window Management -> Window Behavior -> Window Actions,
set "Mouse wheel" to "Maximize/restore"
4. Hover over a window that is not maximized
5. Hold the Meta key and scroll up (or down if Natural Scrolling is enabled)
6. Stop scrolling and release the Meta key
OBSERVED RESULT
When scrolling, the window jumps quickly between maximized and unmaximized.
After stopping scrolling and releasing the Meta key, the window is either
maximized or unmaximized.
EXPECTED RESULT
The window should be maximized and not change its state while scrolling.
