KDE is shifting development focus to Plasma 6.8, with an expected December release window and a major visual overhaul for third-party apps. The highlight is automatic drop shadows, outlines, and rounded corners for client-side decorated windows, which will finally make Steam and Discord blend seamlessly with the Breeze theme. Power users also gain a feature requested nine years ago, as System Monitor now supports CPU affinity to pin processes to specific cores or groups. Meanwhile, ongoing Frameworks and application updates continue chipping away at memory usage, modernizing settings pages to QML, and squashing regressions across the current stable lines.

KDE shifts focus to Plasma 6.8 as CSD shadows and CPU affinity take center stage

KDE has confirmed the bug-fixing efforts for Plasma 6.6.7 and 6.7.4 have wound down, and the team is pivoting hard into feature development for Plasma 6.8. The latest weekly update highlights a major visual overhaul for client-side decorated windows and a system monitor feature power users have been begging for since 2017.

If you've ever opened Steam or Discord on Plasma and noticed the windows looked visually out of place, you weren't imagining things. Electron-based apps draw their own decorations, which meant KWin ignored them for drop shadows, rounded corners, and outlines. Next, Plasma 6.8 fixes this.

Vlad Zahorodnii implemented automatic detection that applies shadows to CSD windows that lack them. The compositor detects the missing visual effects and handles the rest. This approach eliminates the need for users to create manual window rules or tinker with decoration overrides to make third-party apps blend in.

The implementation requires window decorations to declare support for shadow styles in their metadata. It's a solid safeguard, though it means app developers need to play along for the feature to work fully. However, at the same time, Vlad notes that X11 windows get the automatic treatment, while Wayland windows may require a new protocol for opt-in support.

Keep in mind that this isn't just about aesthetics. Vlad detailed the approach on his blog, explaining that forcing the compositor to handle shadows improves consistency across the desktop. Close, maximize, and minimize button alignment still show some inconsistency, a limitation Vlad flagged as a known issue.

CPU affinity finally arrives

In Plasma 6.8, System Monitor gains CPU affinity. You can now pin processes to specific CPUs or CPU groups. Implemented by Taras Oleksyn, this feature has been requested since 2017. Nine years.

Bug #429151 was opened nine years ago. For those who actually use System Monitor for performance tuning, this is a significant win. Pin compute-intensive tasks to specific cores, isolate real-time workloads, or optimize process placement for multi-socket systems.

The feature is powerful, but it's arguably targeting a niche audience given how few people use System Monitor for deep tuning. Still, the long wait is over for anyone who needs to manually schedule processes on KDE.

Other updates and cleanup

Task Manager gets global shortcuts for rearranging tasks and switching between applications. Salman Farooq handled the implementation, adding a layer of workflow efficiency that power users will appreciate.

The Window Behavior page in System Settings has been ported to QML by Tobias Ozór. This modernizes the page to match the rest of System Settings and reduces code duplication. On top of that, Frameworks 6.29 delivers memory reduction through improvements in ksvg and kguiaddons. KDE continues to chip away at resource consumption where possible.

KDE Gear 26.12 removes the Connection Preferences page from System Settings. Tobias Fella noted the settings were esoteric and largely irrelevant in modern use cases. Fair enough. Some cleanup is welcome.

Bug fixes and release context

Plasma 6.7 remains the current stable release, having shipped on June 16, 2026. Plasma 6.6 continues as the active LTS line. Plasma 6.8 is targeting a December 2026 release window, following the standard six-month cadence.

The recent bug-fixing releases aren't totally dead. Plasma 6.7.4 fixed a common Discover crash during updates. Plasma 6.7.3 squashed a regression that caused ksystemstats to crash when waking from sleep, along with hardware-accelerated rendering lag on certain GPU configurations.

On a nostalgia note, Plasma 6.7 also revived the Oxygen theme for KDE's 30th anniversary. It's a nice touch, though it feels more like a heritage project than a daily driver improvement.
