KDE Plasma 6.8.x bug-fix sprint resolves regressions, adds Wayland keyboard layout parity

The KDE Plasma team published its weekly development update detailing an extensive round of bug-fixing across multiple stable release branches, with most regressions introduced in Plasma 6.8 now resolved. Changes landed in versions ranging from 6.6.8 through 6.9, covering panel widgets, Discover, Task Manager, and core shell components. Notable additions include Wayland parity for per-application keyboard layout memory, robust handling of invalid third-party QML shell packages, and multiple crash fixes in Discover's update checker.

The update also brings user-visible polish to the Timer widget, Pager widget icon scaling, and Web Browser widget full-screen behavior. Several long-standing bugs were addressed, including a brightness recovery failure on certain displays, tooltip styling regressions from Qt changes, and panel-cloning screen-affinity issues. The breadth of fixes indicates a coordinated maintenance effort across the entire Plasma stack rather than isolated point releases.

What changed across Plasma 6.6.8 through 6.9

• Wayland input parity: Per-application keyboard layout memory now functions on Wayland as it previously did on X11, closing a multi-year feature gap for multi-layout users.
• Shell robustness: Invalid QML in third-party shell packages no longer triggers infinite crash loops; libplasma now fails gracefully with an explanatory error message.
• Discover stability: Three distinct crash paths during update checking were eliminated in discover MRs #1200, #1446, and #1447.
• Panel and widget layout: The Window List widget now caps maximum title length with text elision, preventing panel overflow; Pager widget icons dynamically scale to fit window outlines at large sizes.
• Qt regression remediation: Multiple fixes address tooltip styling loss and premature text elision in the Icons and Text Task Manager widget caused by upstream Qt changes.

Why it matters

For Linux distribution maintainers shipping KDE Plasma, the concentrated regression cleanup reduces backport workload and stabilizes the desktop experience for users on recent LTS and rolling releases alike. The Wayland keyboard layout fix removes a persistent blocker for enterprise and international users migrating from X11, while the Discover crash fixes improve the reliability of Flatpak and native package updates in Plasma-based distributions such as KDE neon, openSUSE, and Kubuntu.
