KDE Plasma 6.7.4 lands with GPU reset fixes and Wayland polish
The KDE community released Plasma 6.7.4 on Tuesday, the fourth bugfix update to the 6.7 series and a solid step toward 6.8.
The release arrives just three weeks after 6.7.0 shipped, packing fixes across KWin's window manager, the SDDM login screen, and several Wayland protocol improvements. It's the kind of update that doesn't make headlines but keeps AMD GPU users from staring at screen corruption.
Window manager gets the most attention
KWin took the biggest hit in this cycle. The most impactful fix targets libepoxy failures during GPU resets — a problem that's been causing display corruption and crashes, especially on AMD cards under heavy workloads. Two bug reports (#500114 and #519263) are now closed.
There's also a DRM backend fix preventing KWin from incorrectly removing GPUs that have no active display attached. If you've ever had a system with a docked monitor disconnect and the GPU vanish from the taskbar, this one's for you.
SDDM, the login manager, gets wallpaper persistence fixes when monitors are unplugged and reconnected, plus a QML engine crash fix (#523313). The greeter shouldn't dead-lock anymore when you're juggling multiple displays at login time.
Wayland keeps gaining ground
KDE continues chipping away at Wayland limitations. The release adds support for wl_fixes.ack_global_remove, a protocol extension that improves how global surface lifecycles are handled. It's small, but it matters for session stability.
On the desktop side, plasma-setup no longer requires a password when resuming from sleep (#508935). That's a quality-of-life win for anyone running Wayland.
The broader 6.8 preview is already showing multi-GPU performance breakthroughs. Xaver Hugl's work on the linux-dmabuf v6 protocol pushed Cyberpunk 2077 from 27 fps to 50 fps with an RX 5700 XT eGPU at 1440p/120Hz. That's a meaningful jump, and it's coming in the next feature release.
The rest adds up
Plasma Desktop fixes a drag-and-drop regression (#510643) that broke when floating applets were enabled. If you organize your taskbar with grouped windows and floating widgets, this was a real pain point.
Spectacle lets you scan QR codes from previously captured screenshots now, not just new ones. Discover gets UI polish for badge positioning and icon alignment. The digital clock applies font families to timezone labels and fixes resize issues when you toggle seconds display.
Union, the abstraction layer between Qt Quick and Plasma theming, received the largest volume of changes. Animation speed multipliers, CSS input styling, and crash prevention for null values in output widgets all round out the theming stack.
What's next
Plasma 6.8 is already in active development. Recent "This Week in Plasma" posts show emoji picker resizing, pixel-perfect display layout editing with arrow keys, and virtual screencasting no longer locked to 1920x1080.
KDE Linux is 83% complete toward its Beta milestone, with a next-gen QA system catching regressions before users see them. The distro is also integrating kernel-hardening tweaks inspired by SecureBlue.
If you're on 6.7, this is a no-brainer update. Source tarballs are at download.kde.org/stable/plasma/6.7.4. Distribution packages will roll out over the next few days, though KDE neon typically ships within hours.
Keep in mind that KDE neon will likely have this available by tomorrow. Fedora and RHEL derivatives may take a bit longer given their stability-focused release cycles.
