shift+insert (paste)
In the search, it is incorrectly pasted twice.
ctrl + v (paste) → cinnammon
shift+insert (paste) ->cinnamoncinnamon
[cinnamoncinnamon]
Is this in the terminal? Try Ctrl+Shift+V
gnome-terminal , wezterm,tilix.
Ctrl+Shift+V & shift + insert (paste)
Both are normal.
This is not a recent phenomenon,
but a problem I have had for over a year.
$ gpaste-client --raw | head -1
cinnamon
clerical error
not ctrl+insert
shift + insert (paste)
I mistaked.
