I continue to be truly amazed by all the work going into KDE Plasma. Not only is it my desktop environment of choice on Linux, it's Valve's too as it powered the desktop mode on Steam Deck. It's about to get some juicy upgrades too.
Writing in a blog post developer Nate Graham gives an overview of some big improvements coming along to a future version of the Plasma desktop.
The first is you'll finally see fractional scaling on Wayland which was merged in and it should result in scaling having "better performance, less visual blurriness, and lower power usage". Sounds like all of it might not be ready until Plasma 6.0 though due after Plasma 5.27 that releases in February 2023 but it might get backported so we're not waiting so long.
Another issue is the mess that is using multiple screens. They've finally fixed the root cause of the problems with a whole new system of identifying screens that should result in better stability and reliability. Some pretty notorious bugs like desktops randomly losing wallpapers, widgets and various other settings. It won't be perfect but it's not "broken by design" like the old system seemingly was.
There's various other bug fixes, UI updates and more.
One more exciting one I wanted to point out is their new Steam Deck OS (SteamOS) update system. Discover, the software store, now has a backend system to handle SteamOS updates so in future you'll be able to update a Steam Deck from within desktop mode. That sounds mighty useful.
