Installing multiple Desktop Environments?

I was using KDE Plasma on EOS when I started having my video Freeze up problem. See issue freeze up issue

It might be worth a new install of EOS -KDE and see if I still have the problem. It might be safe to include i3 as well so I can test the same applications without the overhead of KDE to see what’s going on. I did get it working with EOS Cinnamon fine.
