For a long time, I have had the same bug here. Most of the time, the copied text appeared in gnome clipboard-indicator, but I had to click it once more there in order to be able to Ctrl-V it (or paste it by mouse/dropdown menu). After reading the discussion here, I followed @Yoannjap (y-jolly)'s method, ie. uninstalled GSConnect, and - it seems that this worked (at least for copying froma Java app and terminal to LibreOffice and Firefox - but there is still a problem eg. with copying from Firefox to Firefox via Ctrl-C → Ctrl-V, while copying via dropdown menu and pasting via dropdown OR Ctrl-V works)...
