I switched from Gnome to KDE (5 Plasma) recently, but am unable to copy text from some applications.
- In Kate, I copy some text (either using ctrl+C, or with right-click-copy).
- I paste (either ctrl-V, or right-click-paste) and some old text gets pasted -- text I copied a few hours ago.
- in the context menu, "clipboard history", I can see the text I just copied, as if it had copied correctly.
- I switch to any other application and I cannot paste that new text either.
It's not specific to Kate:
- Exactly the same problem when copying/pasting in Konsole, and in Dolphin.
But other applications can copy fine...
- I switch to Matlab, and copy some text to the clipboard (alt+W, or right-click-copy)
- I paste the text (ctrl+Y, or right-click paste), and the new text pastes correctly
- I switch to Kate/Konsole, and paste, and the new text copied from Matlab pastes correctly!!!
- Similarly, I can copy text OK from Firefox, and from Libre Office.

So it seems to be copying from specific programs that is broken. Any thoughts on how I can go about debugging this? Is this some incompatibility between GTK, Qt and KDE? I have tried:
- disabling System Tray Settings / General / Extra / Clipboard
- re-enabling Clipboard
- restarting computer of course.
