Seems to affect my system as well. I am on Kubuntu 21.04 with KDE Plasma 5.22.2. Thunderbird is basically unusable on Wayland for me. The whole ui is flickering especially when a reminder notification appears. Thunderbird is the only application that is behaving like that. Firefox runs without problems. I have also noticed graphical artifacts in GIMP when running the Plasma Wayland Session.
