Plasma 6.6.2 Released with Numerous Fixes & Improvements

KDE announced the second maintenance update for Plasma 6.6 major version, that was released 2 weeks ago.

This version features translation updates, various stability fixes, and some improvements to the built-in components.

First, it changed the way it sorts the session in Plasma Login Manager. When no previous session exists to remember, it will sort Plasma sessions first, then sort alphabetically, and then sort Wayland first.

So, it will show you desktop sessions in following order: Plasma (Wayland), Plasma (X11), Plasma Bigscreen, Plasma Mobile, and non-plasma sessions in alphabetical then Wayland-first order.

KRDP, the remote desktop protocol, got some fixes in the release. It fixed scrolling issue from clients using high resolution (“pixel perfect”) mouse or touchpad input.

As well, it fixed thread safety issues in VideoStream, potential freeze, and rendering artifacts or black screen when connecting from Windows clients.

For users of Oxygen theme, this version fixed the indication in the panel when an app is minimized and sizing issue for apllication launcher scrollbars.

It also changed the way it handles apps lying about having a menu. It will disable the button if an app gives an empty menu, prevent user from hitting it while the menu is still being fetched, and make sure the menu is not empty before showing it.

For laptop users with external monitors connected, it fixed the issue that charge state profiles could mess the screen priority or ordering after plugin-in or unplug the charger.

The version also includes various crash fixes. Plasma 6.6 introduces support for custom Wayland modeline via kscreen-doctor, allowing to set custom resolutions and/or refresh rates. However, when create a custom modeline if you are already in one will crash and restart the desktop.

Spectacle crashed when attempting to share a rectangular selection screenshot via KDE Connect. And, shortcuts settings page crashed when typing a character and a plus sign in the search bar. Now, all these crashes have been fixed.
