Description Lyubomir 2021-12-16 23:48:14 UTC

SUMMARY
Probably two issues, or maybe not.
- Copying something from Firefox (& maybe from other apps??) sometimes does not show up in the "Clipboard contents" system tray applet. Then i cannot paste it into other apps (Chrome, Kate, Application Launcher search field) neither with Ctrl + V, nor with context menu. In addition after i try to paste it the app into which i try to paste freezes for a while (4-5 seconds).
- If i copy from Authy snap some 2FA code and close the Authy app i'm not able to paste it. It has to be still opened to paste successfully.

STEPS TO REPRODUCE
1. Copy something from Firefox
2. Try to paste into Kate/Google Chrome/Application Launcher search field

OBSERVED RESULT
App freezes for a while

EXPECTED RESULT
No freeze should happen. Should paste successfully.

I should say that when i copy from Authy the code appears in the system tray clipboard applet, but still doesn't paste if Authy is closed. Let me know if these should be two bugs.

Similarity to Bug 433854 ?

I still encounter the "obstinacy" with Firefox described in
   https://bugs.kde.org/show_bug.cgi?id=433854#c7
Often see the issue when running client VM's and trying to cut and paste from one to another. See the "5 second freeze" when trying to paste.

There is the workround of clearing the clipboard history and trying again. It sometime helps, not a golden bullet.

Apparently the OP in Bug 433854 can't paste into other tabs but i think i can do that, just can't paste into other apps. I'll have to try it the next time a little more. Hasn't happened today and maybe yesterday i believe.

For copying from firefox causing a freeze see:
https://bugzilla.mozilla.org/show_bug.cgi?id=1722369

For other plasma issues see the related bugs already cited. Though we need to narrow things down a lot more to be useful
