Can I test wayland on Kubuntu 20.04

Operating System: Kubuntu 20.04 KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 Kernel Version: 5.8.0-50-generic OS Type: 64-bit Processors: 4 × AMD Ryzen 3 2200G with Radeon Vega Graphics Memory: 29.4 GiB of RAM

I have tried following advice for Ubuntu desktops, but that doesn't seem to apply to Kubuntu. I have some strange video issues where random x-windows stop updating or repainting the screen. It happens when watching videos with SMPlayer and VLC and in Firefox and Thunderbird. Even the plasma panel will get in on the action with flickering titles or the digital clock will stop working. I have to change any of the Compositor settings to get windows to start updating again. Turning off the Compositor accomplishes nothing. I'm not finding any help for these issues so thought of trying out Wayland. Will I have to update to 21.04 before I will be able to start a Wayland session?

Yes, you can. You need to install plasma-workspace-wayland

sudo apt install plasma-workspace-wayland

logout and log back in selecting the plasma wayland session.
