With the recently released KDE Plasma 6.1 desktop environment, those still relying on old Intel integrated graphics should have a much more pleasant experience thanks to improvements made to the KWin compositor. For very old Intel integrated graphics, it can effectively be a night and day difference upgrading to the new Plasma 6.1 desktop.
KWin lead developer Xaver Hugl is out with a new blog post about the improved KDE Plasma desktop performance as of Plasma 6.1, which can be especially noticeable with old integrated graphics hardware such as the common Intel graphics in aging laptops. The biggest improvement to bettering the KDE Plasma desktop graphics performance is thanks to dynamic triple buffering support.
Why are you excited about cosmic? I haven’t kept my ear to the ground, this is the first I’m hearing about it.
It’s a new desktop by the Pop!_OS team, System76. They previously used Gnome extensions but to make a snoother, more performant experience, they have been working on an entirely new desktop environment + toolkit, all in Rust. They call it Cosmic.
The new Cosmic Store is super fast and smooth, perhaps the fastest package manager GUI on Linux desktop.
