[1]KDE Plasma 6.4.0 brings improved handling of window tiling, refinements to its dark mode, tweaked widgets and notifications, better sorting of search results from the built-in Krunner tool, a revamp to the screenshot tool Spectacle, among other things. The [2]full changelog is nearly 3,500 lines long, so this is a significantly different release.
It's only about four months since we [3]covered the release of version 6.3 . That arrived one year after the [4]long-awaited release of Plasma 6.0 , a full decade after [5]Plasma 5 . After such a long time, the release schedule for 6.x feels rapid, as if the team is enjoying working on the fresh new version. There is a pre-planned [6]release schedule , which indicates that Plasma 6.5 should arrive around October.
[7]
Right now, though, 6.4 is so new that on the day of release, the project's showcase distro, [8]KDE Neon , had not yet been updated and still included version 6.3.5 of the desktop.
The bigger context
Right now, KDE Plasma enjoys two significant advantages over almost all other FOSS desktops. One is that it has full built-in support for Wayland. That means that KDE and GNOME are pretty much the only full-fledged desktops with native, integrated Wayland support. Most of the other Wayland environments currently available are much simpler tiling-windowing systems, which are mainly aimed at the sort of user who mainly lives and works in shell windows and doesn't want a full desktop.
The other thing is that KDE is not just a Linux desktop. It also runs on both FreeBSD and OpenBSD (both NetBSD and DragonflyBSD include the older KDE Plasma 5). As we [9]reported last week , as well as dropping X11 support, the GNOME project is planning to [10]introduce stronger dependencies on systemd . Since systemd is Linux-only, that effectively means GNOME is well on the way to becoming a Linux-only desktop – it will make life much harder for developers of other OSes to support GNOME. This could be good news for the cross-platform KDE, GNOME's slightly older and most popular rival.
[11]
[12]
The teams behind multiple other FOSS desktops are working hard on their Wayland support, and among those with preliminary or experimental support are the latest versions of LXQt, Xfce, Cinnamon, and Budgie. Even if the [13]recently announced Xlibre fork of the X.org X11 server succeeds, though, there are many older desktop environments not in active maintenance that will very probably never make the leap. This ranges from old-timers such as [14]CDE and its lookalikes to more recent projects such as the [15]Unity desktop and [16]LXDE – not to mention dozens of simpler window managers.
What's new?
Although Plasma is based around the model of stacked overlapping windows, it does have built-in tiling support, much like modern Microsoft Windows since Vista's Aero Snap. Drag a window to any screen edge, and KWin will offer to tile it to that edge or corner. What's more, it will then also offer to resize any other visible window next to it. Not only can you choose different layouts, such as grids, horizontal rows, or vertical columns, but now, in this release, KWin will remember different layouts for different virtual desktops.

The team has put work into improving accessibility, especially while using Wayland, with new keyboard navigation features, including the ability to control the mouse pointer via keyboard and support for multi-finger trackpad gestures to zoom in and out. The desktop now has more visual contrast, using shading to emphasize dialog boxes and make them easier to find. The dark mode now uses deeper tones and increased contrast. Controls for animations have been brought together into one place, making it easier to adjust them – or simply disable them, which makes things easier for some people. This even extends to the lock screen, whose controls now follow the mouse from one monitor to another.

Notification handling has been refined. There's an automated Do Not Disturb mode when in full-screen apps, such as games or movie players, and a history summary waiting for you in the system tray when you return to the desktop. If you mute the microphone, Plasma 6.4 will remind you when you try to use it. This is a welcome contrast to the GNOME design, which seeks to eliminate things like status icons and pop-up notifications.
Many of the individual widgets and apps have been tweaked. Some are relatively minor: the app launcher highlights new apps, file progress dialogs show the transfer speed, and the media player lets you adjust playback speed. Some have had more significant changes: the menu editor and screenshot tools have been redesigned, and the Disks & Devices tool now offers options to check and repair volumes.
There's improved management of graphics tablets and display color profiles, including for high dynamic range displays. These changes go some way to rectify the issues [22]reported by artist David Revoy last year.
[23]
Rolling-release distros will get Plasma 6.4 very soon, but it's too late for the forthcoming Debian 13. That [24]will use Plasma 6.3.5 . Plasma 6.5 is scheduled for around the same time as Kubuntu 25.10 this autumn, meaning that it will probably be too late for inclusion – the next Kubuntu will probably use a later version of 6.4.x.
Bootnote
We checked again on Wednesday and the User Edition on the [25]KDE Neon downloads page still hasn't been updated to the new Plasma release. A day after release, post-install, users must download and install nearly 400 MB of updates to get Plasma 6.4.0. On release day, the Testing edition still had a late beta version – and failed to install correctly in our testing.
[26]
KDE Neon upgraded to Plasma 6.4.0. The Wayland session works well, but as the terminal shows, it's no lightweight desktop – click to enlarge
We tested in VMware because under Virtualbox, Neon showed the same display corruption [27]we saw in Fedora 39 two years ago . Even so, once upgraded to 6.4, we found that the X11 session was unusable. kwin crashed immediately, so we couldn't move or close windows. Wayland worked, but captured the mouse pointer, and the desktop did not resize with the VM's window.
While we are pointing out such issues, we note that the Testing and Unstable editions share identical descriptions, which is not at all helpful. The two versions urgently need better descriptions to differentiate them. Speaking of which, the description of the Developer Edition contains a typo:
Unstable Editon [sic] plus development libraries pre-installed.
Some critics will doubtless complain that we are quibbling, but we find such lack of attention to detail worrying. ®

Re: Remind me
KDE has actually one of the better Wayland implementations (with a bunch of additions to make it reasonable).
But, yeah. The entire debate has always been between ‘we have this software and users love how it works across all platforms – except it breaks in Wayland because [SOMETHING] is impossible by design there’ and ‘we have this grand philosophy how GUIs should work in abstract and if you do not write your synchrotron control system to work with windows wrapped around a 3D bunny rabbit[*] you are a bad person’.

Easily fixed typos, and Apple stubbornness
> Some critics will doubtless complain that we are quibbling, but we find such lack of attention to detail worrying.
Indeed. This is probably just a typo in this case, and easily fixable. But what about when it is Apple, and the issue is reported to them several times? On the iCloud web interface, under Account/Aliases is this charming phrase exactly as is: Aliases cannont be changed or transferred.
I spotted this ages ago and reported it to Apple. It was still there a couple of weeks ago. I reported it again. It's still there now. Apparently Apple cannont fix this. At this stage I presume I must be reading it wrong.
> ....complain that we are quibbling, but we find such lack of attention to detail worrying.
Hear hear! One reason I cling to MS software is mediocre proof-reading. As opposed to the lame stream-of-consciousness proofreading in most "linux" softwares. They know what they wrote and can't be arsed to check it, or get an innocent to read it. That's not just my mom's(*) genes lingering through the years. Program code is VERY prone to typos, and a pain to proof-read. Yes, I read Code Complete which implied that MS coders could screw-up Bill Gates' birthday card. Bad as MS is, most linux-world documentation and code seems to be worse.
Won't run right under Virtual Box? That's fatal right there-- Influencers and reviewers will start on a virtual machine to save risk and time, and VB is an obvious choice.
> Testing and Unstable editions share identical descriptions, which is not at all helpful.
BTW, putting the same caption on two different photos is another sort of typo which gives me no confidence in code quality.
(*) Mom was an old-school newspaper editor with decades of experience in spottting tipos.
neon neglect
Well, not surprising that they did not tend to a contemporaneous update of neon. They failed to give sufficient attention to their showcase distro before. Since the disaster roll out of Plasma 6 on Feb. 29, 2024, I wouldn't touch neon with a 10 foot pole. (My machines run kubuntu and debian kde since then.)
Remind me
Who is it of the users that asked for a replacement for X11, that doesn't work?
Enquiring minds want to know!
