This Week in Plasma: Finalizing 6.6

Saturday, 14 February 2026  |  Nate Graham, and John Veness

Welcome to a new issue of This Week in Plasma!

This week we put the finishing touches on Plasma 6.6! It’s due to be released in just a few days and it’s a great release with tons of impactful features, UI improvements, and bug fixes. I hope everyone loves it!

Meanwhile, check out what folks were up to this week:

Notable UI Improvements

Plasma 6.7.0

Moved System Settings’ “Remote Desktop” page to the “Security & Privacy” group in System Settings. (Nate Graham, krdp MR #139)

Improved the way loop devices are handled in the Disks & Devices widget. (Bogdan Onofriichuk, plasma-workspace MR #6260)

Reduced visual jagginess in the split image effect of wallpaper previews that show both a light and dark version. (Fushan Wen, plasma-workspace MR #6283)

The Kicker Application Menu widget now supports using a non-square icon for its panel button, just like Kickoff does. (Christoph Wolk, plasma-desktop MR #3522)

Added a dedicated global action for un-tiling a quick-tiled window. It doesn’t have a keyboard shortcut by default, but you can assign one yourself. (Kevin Azzam, KDE Bugzilla #500636)

Videos in SDDM login screen themes can now be previewed in System Settings. (Blue Terracotta, sddm-kcm MR #99)

Improved the appearance of various dialogs created by KWin. Read more here! (Kai Uwe Broulik, kwin MR #8702)

You can now configure how long it takes the window switcher to appear after you start holding down Alt+Tab. (Guilherme Soares, KDE Bugzilla #486389)

Frameworks 6.24

In Kirigami-based apps, hovering the pointer over buttons that can be triggered with keyboard shortcuts now shows the shortcuts. (Joshua Goins, kirigami MR #2040)

Gear 26.04.0

Setting up a Samba share for one of your folders so people can connect to it over the network now turns on the Samba service (on systemd-based distros) if needed. This completes the project to make Samba sharing relatively painless! (Thomas Duckworth, KDE Bugzilla #466787)

Notable Bug Fixes

Plasma 6.5.6

Monitor names shown in the Brightness & Color widget now update as expected if you connect or disconnect them while the system is asleep. (Xaver Hugl, KDE Bugzilla #495223)

Fixed multiple issues that caused custom-tiled windows on screens that you disconnect to move to the wrong places on any of the remaining screens. (Xaver Hugl, kwin MR #7999)

Plasma 6.6.0

Hardened KWin a bit against crashing when the graphics driver resets unexpectedly. (Vlad Zahorodnii, kwin MR #8769)

Fixed a case where Plasma could crash when used with the i3 tiling window manager. (Tobias Fella, KDE Bugzilla #511428)

Fixed a potential “division by 0” issue in system monitoring widgets and apps that messed up the display percentage of Swap sensors on systems with no swap space. (Kartikeya Tyagi, libksysguard MR #462)

Worked around a Wayland bug (yes, an actual Wayland bug — as in, a bug in one of its protocol definitions!) related to input method key repeat. Why work around the bug instead of fixing it? Because it’s already fixed in a newer version of the protocol, but KWin needs to handle apps that use the old version, too. (Xuetian Weng, kwin MR #8700)

Unified the appearance of HDR content in full-screen windows and windowed windows. (Xaver Hugl, KDE Bugzilla #513895)

Fixed a layout glitch in the System Tray caused by widgets that include line breaks (i.e. \n characters) in their names. (Christoph Wolk, KDE Bugzilla #515699)

The Web Browser widget no longer incorrectly claims that every page you visit tried to open a pop-up window. (Christoph Wolk, kdeplasma-addons MR #1003)

Fixed a layout glitch in the Quick Launch widget’s popup. (Christoph Wolk, kdeplasma-addons MR #1004)

You can now launch an app in your launcher widget’s favorites list right after overriding its .desktop file; no restart of plasmashell is required anymore. (Alexey Rochev, KDE Bugzilla #512332)

Fixed an issue that made inactive windows dragged from their titlebars get raised even when explicitly configured not to raise in this case. (Vlad Zahorodnii, KDE Bugzilla #508151)

Plasma 6.6.1

When a battery-powered device is at a critically low power level, putting it to sleep and charging it to a normal level no longer makes it incorrectly run the “oh no, I’m critically low” action immediately after it wakes up. (Michael Spears, powerdevil MR #607)

The overall app ratings shown in Discover now match a simple average of the individual ratings. (Akseli Lahtinen, KDE Bugzilla #513139)

Searching for Activities using KRunner and KRunner-powered searches now works again. (Simone Checchia, KDE Bugzilla #513761

Frameworks 6.24

Worked around a Qt bug that caused extremely strange cache-related issues throughout Plasma and Kirigami-based apps that would randomly break certain components. (Tobias Fella, kirigami MR #2039)

Notable in Performance & Technical

Plasma 6.6.0

Added support for setting custom modes for virtual screens. (Xaver Hugl, kwin MR #8766)

Added GPU temperature monitoring support for additional GPUs. (Barry Strong, ksystemstats MR #123)

Plasma 6.7.0

Scrolling in scrollable views spawned by KWin (not Plasma, just KWin itself) no longer goes 8 times slower than it ought to. Thankfully there are very few such views, so almost nobody noticed the issue. However fixing it facilitates adding a “scroll to switch virtual desktops” feature to the Overview effect for Plasma 6.7! (Kai Uwe Broulik, kwin MR #8800)

Frameworks

Moving a file to the trash is now up to 50 times faster and more efficient. (Kai Uwe Broulik, kio MR #2147)
