has a tendency to crap the bed a few minutes after startup
Tell me you are an nvidia user without telling me. Either that is hard to believe. I use KDE daily for more than 8-9 hours a day, sometimes my pc goes for a full week without geting turned off, multiple apps tabs and servers on, themes installed, widgets on the desktop, I am such an extremely heavy KDE user you have no idea. Still, zero crashes. Sometimes something goes a bit “wut” like moving a window around gliches a liiiiiiitle bit, but it instantly corrects itself and goes back to being stable. And I am on Plasma 6.0.3, funny enough has been more stable than Plasma 5.
Update your KDE or use a distro that has better KDE support. Some distros fck up KDE packages and get it unstable. Fedora KDE is rock solid for example. Nobara has been great too and its now KDE by default.
