Man, I really like KDE, it is my preferred desktop on Linux, but something is going on. I downloaded the most recent version of Kubuntu to set up a new Linux desktop and it was unusably buggy. I first blamed my Nvidia card but after switching around between drivers I couldn’t make anything work. Animations would glitch, apps would randomly crash, etc. I eventually installed XFCE and it’s rock solid. I hope going forward some of these stability issues can be fixed.
