> When I switched to KDE/Plasma 5 to get fractional scaling it was extremely unstable

KDE Plasma 6 made major improvements and has excellent fractional scaling, the best I've seen in a Linux desktop environment and comparable to scaling in Windows 10-11. I encourage you to give it a try.

Sorry I misspoke - I was using Plasma 6, as that was the only way to get fractional scaling in X11 apps
