When creating a new folder, the content copied to the clipboard disappears

Help
1

When I use KDE to create a folder or file, the text I copied beforehand disappears when the pop-up window appears. Is this normal?

I imagine you’re using Wayland?

In any case, please provide some info about your system using the command below in a terminal and then copying the output and pasting it here.

kinfo

Also, to confirm, you mean when using the KDE file manager, Dolphin, correct?

Yes, I’m currently using Wayland.

Here is my system information:

Operating System: Fedora Linux 44
KDE Plasma Version: 6.7.4
KDE Frameworks Version: 6.29.0
Qt Version: 6.11.1
Kernel Version: 7.1.12-200.fc44.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 12 × 12th Gen Intel® Core™ i5-12400F
Memory: 16 GB of RAM (15.4 GB usable)
Graphics Processor: NVIDIA GeForce RTX 3060

My file manager is Dolphin.

Some questions:

  • Are you new to KDE? If not, when did this issue start?
  • Does this bug consistently happen or is it random?
  • Does it happen when copying text from within Dolphin, or only from other apps?
  • Have you tried X11 or another Wayland user profile to see if the issue persists?

I started using KDE about a month ago, and this has happened every time I try to create a new file. So far, I’ve only noticed the clipboard contents disappearing when naming a new file in a Dolphin window. I haven’t tried X11 yet.

Yes, but where are you copying the text from? Is it from a file within Dolphin or from another application, like a web browser? Trying to identify where and when the clipboard fails to do what is expected.

Text I copy from other software, such as Chrome

Okay. So, unfortunately, due to Wayland’s security architecture, this happens infrequently on some users’ systems. It’s getting better, though. I run an Arch-based distro, so it is possible that the next update you get will fix the issue.

For reference:

Operating System: Archcraft 
KDE Plasma Version: 6.7.4
KDE Frameworks Version: 6.29.0
Qt Version: 6.11.2
Kernel Version: 7.2.2-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i7-7700HQ CPU @ 2.80GHz
Memory: 16 GiB of RAM (15.3 GiB usable)
Graphics Processor 1: Intel® HD Graphics 630
Graphics Processor 2: Quadro P3000

There’s not much difference between what you have and what I have, but that very small Qt Version: 6.11.1 vs Qt Version: 6.11.2 can make a difference.

It could also be a Chromium issue, as this does not happen when copying from Firefox for me. One second while I check with Brave and Vivaldi.

EDIT:
No issue in Brave or Vivaldi. Can only assume it’s the Qt version.
But also, have you tried this?

Creating a new user account and testing for the same issue can help to identify if the issue is user settings-related or an actual bug.

Do you mean it disappears from the clipboard history applet and/or that it just vanishes and you can’t paste it anymore? Maybe something in that process is overwriting the clipboard, but even then it should remain in the clipboard history if that was the problem.

10

Yes, it was saved to the clipboard history, but when I tried to paste it into Dolphin using the shortcut key, it didn’t work—I had to copy it again.

In your clipboard configuration, do you have “Keep the selection and clipboard the same” enabled? If so, try disabling it and then test.

My testing: Dolphin 25.12.3, Kubuntu 26.04

This issue appeared after upgrade to Kubuntu 26.04. It appears to be a bug in Dolphin where creating a new folder or text (via right-click menu) and then pasting at the prompt will instead paste an empty string.

When using F2/Rename for an existing file/folder the paste will work as expected.

My workaround is to do the ‘create new folder’ action to get the prompt open (leave it open), go to the other app, copy what text I need, then go to Dolphin and paste in the waiting prompt.

That sounds like this bug: https://bugs.kde.org/show_bug.cgi?id=517780
Which at least on my rolling system has been fixed for a while now.
