Bug 424649

Is the pasted text making it into Klipper?

(In reply to Nate Graham from comment #1)
> Is the pasted text making it into Klipper?

The text appears in the popup of clipboard applet after I press ctrl+c.

I can reproduce all three cases, however the other way around (from anything to Kate) is not reproducible, Kate uses the clipboard as intended.

I don't have time to test on a recently compiled version from master, but is this still happening there?

Might have been fixed by https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/1.

This should be fixed as of 5.20. Please reopen if it's not the case.

This problem persists.

Operating System: Arch Linux
KDE Plasma Version: 5.20.1
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1

Can reproduce all three cases with a git master Wayland session. I suspect this is a big part of the remaining complaints about the clipboard not working properly on Waylane

Notably, if I click on the entry in Klipper for the text, then pasting works. So it looks like Klipper is somehow not being made aware of it automatically, or something.

I can also reproduce this bug on my Fedora 34 (KDE spin) system.

Can also confirm; glad I'm not going crazy, the consistently inconsistent CTRL+C failures were driving me nuts (even having some Cut actions fail after the original selection was deleted, ie text).

For now using explicit right-click menu commands seems to work around the issue for me, but using keyboard commands is... spotty for now

I can reproduce all cases, except that it is enough to open the klipper menu and see that the copied text is there (before closing the application) for the content to be available for pasting.

I would like to add that this issue exists when using Inkscape not just in Wayland but when in X11 as well. Moreover, guessing firefox/chrome/libreoffice are gtk apps, I did not have any trouble pasting the copied text from kate/kwrite (after closing it) to firefox/chrome/libreoffice.

Moreover, I observed that the problem with Inkscape could be temporarily resolved if "ignore selection" is enabled in klipper settings. 

Thus, with my limited understanding, I would like to add that the DE may not be causing this. However, I am unsure whether this is an issue with klipper or is specific to Inkscape.

Please note that by DE I actually meant the display server. Apologies for the error.

Cannot reproduce.

Gedit 3.36.2
Gtk 3.24.20

Can anyone confirm if it's working for them too on 5.22?

Not sure about Gedit, but the issue could still be observed when using Inkscape (both versions 0.92 as well as 1.1) in KDE v5.22.

Ok, I can reproduce the issue with both Gedit and Inkscape, only if "Prevent empty clipboard" is turned off in Klipper settings.

My other Klipper settings, may be relevant:
- Save clipboard contents on exit: YES
- Prevent empty clipboard: NO
- Ignore images: YES
- Ignore selection: NO
- Text selection only: NO
- Sync clipboard and selection: NO

Turning on "Prevent empty clipboard" (which is on by default), makes the bug disappear.

I can confirm that. When "Prevent empty clipboard" is on, everything works fine. When it's off, this breaks, and (ironically) an empty entry appears in Klipper when I copy the text in Gedit. Lowering priority as there is a trivial and non-destructive workaround and also this works with the default settings.

Settings and Blank Clipboard Confirmation

Not to be contrary, but at least with specifically Firefox (91.0.2), this is still an issue on my Fedora 34 KDE install. It does appear this is even with the "Prevent empty clipboard" checked, there are still *some* times where blank clipboard entries occur. See highlighted attachment

Were you copying text from the webpage, or from the addressbar?

For some reason, the former works for me reliably, while the latter often doesn't and inserts a blank entry instead.

Just text on a page, but happens to me often enough I forgot to mention that, sorry!

"text/plain;charset=utf-8" isn't treated as being text.

Should hopefully be a fast fix.
