Over a month after Plasma 6.3.4 was released, the KDE team rolled out version 6.3.5, the fifth (and last) bugfix update to its 6.3 series, before Plasma 6.4, scheduled for mid-June.
In this release, Breeze, KDE’s default theme, receives some tidy-ups, including a missing QDebug in Kcursorgen and a handful of other header fixes. Meanwhile, Discover’s storefront interface sees improvements to its “Still Looking” indicator and fixes the offline update header text on narrow windows.
Moreover, several applets benefit from targeted adjustments. The Notes applet no longer imposes unnecessary size constraints, and weather widgets now more consistently respect default units. Likewise, URLs in bug reports have been corrected, so filing feedback is much more straightforward.
Under the hood, the most substantial work happens in KWin and KScreen, where several commits tighten up rendering, input handling, and display management.
For instance, the VRR scheduler now correctly factors in subsurfaces, texture allocation guards prevent zero‑size crashes, and HDR brightness settings get fine‑tuned for consistency.
Additionally, a fix ensures that power‑button presses don’t slip through to the lock screen, and the nightlight plugin now reliably converts between local and UTC. On the screen‑management front, KScreen’s OSD manager is instantiated at exactly the right moment, and settings correctly revert when you back out of changes.
Beyond the compositor, core libraries such as libksysguard and libplasma receive stability tweaks, like initializing NVIDIA process counts to zero and using proper Kirigami properties for colors.
Desktop components also get their share of love: task‑manager dialogs won’t rotate unexpectedly, activity switchers track coordinates accurately, and recent‑files grids respect hover disabling.
Lastly, the vault toolchain and print manager see minor corrections, such as enabling default printer selection when adding new devices.

As always, if you’re using a rolling release distro, keep an eye on your distribution’s repositories—version 6.3.5 is expected to land there in the coming days or weeks.
