Bug 424725

You said:

> Reboot doesn't solve.
And:

> I'm not able to reproduce this because it's happening right now.

So what solved it? Did it just randomly stop happening?

Nothing that I tried solved, including recreating the panel, defaulting the clipboard settings. Even reboot doesn't help.

Ops, sorry. I meant "I'm not able to trigger this bug manually, because it's still happening", in other words, I can't stop this bug to reproduce it again.

I see, so it's always happening.

Works for me on 5.19 and git master FWIW.

Can you run `plasmashell --replace` in a terminal window and then click the clear button and tell me if anything appears in the terminal window right afterwards?

plasmashell --replace doesn't solve

It didn't work. I attach a video showing that it didn't solve.

That wasn't supposed to solve the problem but rather provide logging information that might help me debug the issue. Can you provide the logging that I requested?

Oops, I recorded 2 videos, one of them was with terminal, but I got worried. Does the output include personal info?

No. :)

plasma-shell --replace on terminal

Done!

I need to see the terminal output when you press the "clear history" button. :)

But I did press it and no output was created. Sorry, what I need to do?

I didn't see you press the "clear history button" in that video. Are you saying you clicked it while not taking a video and nothing happened?

plasma-shell --replace 2

Done!

Thanks!

Sadly you were right, no special output. That makes this a bit weird.

Heh, I know what this is.

Can I see your ~/.config/plasmashellrc

Do you have the lines:

After changing it to true and running plasma-shell --replace, it started to work again! But wait, why this happened?

There's a prompt "Do not ask again" on the dialog that shows the message

"Are you sure you want to clear the history"

at some point you've pressed that no you're not sure you want to clear and you don't want to be asked again.

It behaved in a way that is "technically correct" even if it's not super intuitive.

Not useful either, since it gets you into a broken state.

This is a great candidate for showing an inline Undo post-clear instead of a confirmation dialog pre-clear. That's what Elisa does when you clear the playlist and It's a way better UX IMO.

Understood! Furthermore, there's no setting available in clipboard settings to restore the confirmation dialog, so the user indeed gets in a broken state.

A "undo changes" banner with an "undo" button is also a great solution. I prefer this one.

A post-clear undo is not a viable option for an action that's about deleting private information as in order to work it would have to not delete it.

Elisa puts the undo action for playlist clearing on a timer. It's visible for IIRC 7 seconds, and after that, the option to undo clearing the playlist the disappears. So for Klipper, we could do the same thing: the cleared data could be secretly kept around in the background for a few seconds while the user has a chance to undo it, and after that, both the cleared data and the undo option would disappear.

This is also how many mobile apps handle similar situations. And I'd encourage you try it out in Elisa if you haven't used it before. It's quite user friendly.
