Description Tomasz Hołubowicz 2024-10-14 19:28:27 UTC

SUMMARY
Disabling "Pastes selected text" for middle-click (almost) disables Emacs clipboard synchronization. 

STEPS TO REPRODUCE
1. Disable "Pastes selected text" setting and restart system.
2. Open Emacs and try to copy text with M-w (kill-ring-save) or C-w (kill-region). 
3. Try to paste text or open history popup.

OBSERVED RESULT
Nothing gets saved to system clipboard. Weirdly enough C-k (kill-line) or C-M-k (kill-sexp) still saves things to clipboard. 

EXPECTED RESULT
Copying and cutting text in Emacs works as usual.

If emacs is using the primary buffer (middle click paste) buffer for storage, and we disable it there's nothing we can do at our level.

You can try reporting it to emacs.
