The bug-fixing marathon continued this week, alongside an avalanche of new bug reports! It appears people are indeed testing the Plasma 6 beta release, which is great! Fortunately most of the bugs …
Plasma 6 is currently in beta, so it really isn't meant to be used for anything other than testing. I have it installed on arch, and honestly it's good enough for my use with wayland, but you will definitely will run into issues. I also use Nvidia, though, so I'd probably have more issues than you will.
Overall, I only recommend it right now if you can roll back or if it isn't that big of a deal if your install breaks.
