Description Patrick Silva 2020-04-18 12:41:32 UTC 
STEPS TO REPRODUCE
1. use the clipboard applet in systray to make sure that your clipboard is empty. If it is not, empty it.
2. open Kate
3. right-click on the text area: "Paste" entry is enabled.
Click on "Edit" menu: its "Paste" entry is enabled too.

EXPECTED RESULT
"Paste" entry of menu bar and context menu should be disabled when there is nothing to paste.

Comment 1 Patrick Silva 2020-04-19 13:53:22 UTC 
it's not a Kate issue. Konsole is also affected and sometimes I can't paste
copied text. Re-assigning to klipper.

Not a plasmashell bug.
Comment 4 David Edmundson 2021-10-03 19:47:14 UTC 
Reproducible on x11 too.

QClipboard does get notified when clipboard is emptied.

It will add a noticable amount of overhead to have apps update and check, we hit a noticeable slowdown with QQuickTextInputs check. If someone makes a one line obvious fix in KStandardActions, please check that properly.
