Hello, I have been trying to install KDE on Arch (or anything based off of it). However, I have been unable to use it as the performance is completely unusable. This happens on both Wayland and X11 Plasma, but not other DEs (e.g. XFCE), even with the Mesa drivers. I’ve only found one other post talking about this with no fix. I can confirm that Plasma does run on it as I’ve ran Kubuntu 24.06 - 26.04 LTS on it.
