[Bug 1932328] Re: Thunderbird under Wayland does not correctly close (or manage) windows

[Heiko Gimbel]

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.
