Doing what you suggests does put the text in the systray clipboard and then using Ctrl-V in Thunderbird does past.  But the "paste" key on my trackball pastes text previously highlighted within Firefox (for example). It can be confusing to me to have to remember 2 methods depending on what apps I'm using. Would be nice if this were unified. -- Remind me to ignore comments which aren't germane to the thread.

It very much sounds like that bug. In fact, KDE maintains a list of "Showstopper bugs" (https://community.kde.org/Plasma/Wayland_Showstoppers) and this is one of them. There are currently three showstoppers which related to copy&paste issues under Wayland: https://bugs.kde.org/show_bug.cgi?id=424754 https://bugs.kde.org/show_bug.cgi?id=424649 https://bugs.kde.org/show_bug.cgi?id=434675 I ran into similar issues when trying to copy&paste things from Firefox or Google Chrome (both use XWayland by default). The solution for Chrome was to use the Wayland backend following the instructions in the Arch Linux wiki (https://wiki.archlinux.org/index.php/Chromium#Native_Wayland_support): $ google-chrome-stable --enable-features=UseOzonePlatform --ozone-platform=wayland I get a feeling that the whole Wayland by default thing in Fedora 34 is not really well tested and has still a lot of rough edges (I have hit already three of the showstopper bugs listed at the KDE webpage and switched back to X11 as KDE Wayland is clearly not yet ready for use in a production environment). Hope this helps. Armin

This is a very windows-like method to copy/paste text and is only useful for occasional users - not for users constantly copying and pasting. For a long time Linux has this copy by just selecting text (called primary selection) as well regular copy/paste with keyboard or mouse right click. X11 has separate protocols for these. Also clipboard managers exist since a long time to keep a hstory of your clipboard which is also very useful and is an instrumental feature for me. Honestly I'm baffled how many users work without this. Now clipboard managers can be configured to put primary selection into history or not. Also they can be configured to sync clipboard and primary selection or not (so that you have something in clipboard and something else in primary selection and paste with middle click or keyboard/right-click). Lately I tend to prefer syncing primary selection to clipboard due to issues with primary selection in browsers. If not for that, I'd keep them separate. Anyway, the thing is that Wayland handles clipboard very differently thus window compositor and the clipboard manager need to work hard to keep existing X11 convenient behavior. From the thread it sounds like Gnome got it right already but not KDE unfortunately. Although officially it seems supported and the KDE clipboard manager `klipper` has the right options, they simply don't work for me. I came to this mailing list to seek help, only to find out the upstream blocker bugs above. I guess I keep choosing X11 on login 2 more years until things are ironed out. I was thinking it is finally possible to migrate to Wayland but it isn't because clipboard is a show-stopper for me. Too bad Fedora switched to Wayland by default for KDE before it is ready. I also hit other issues with kwallet being broken for me, especially under wayland the gpg dialog appears under other windows, failure to unlock wallet results in freezes, as well touchpad applet can't enable/disable touchpad. Also kwallet is unable to work with GPG for me. Spills out invalid key or something which is not true as it worked in the past and gpg is working for me. Good that under X11 this is not distracting and I don't really use kwallet anyway. So for any users that are bugged with strange behavior, I'd suggest to report your bugs to KDE bugzilla and switch to X11 until the next iteraiton. So thank you for the information.
