[Gwenview] Copy to Clipboard

For some reason when I use this, I cannot paste the results?

The first result is a screenshot from a spectacle and below that are two gwenview screenshots:

Is it posting metadata as well perhaps?

Be more specific.

Let’s see -


Image copied from Gwenview appears in Klipper…

  1. Open Gwenview
  2. Open relevant image
  3. Right click image and select copy
  4. Hit Ctrl+V (Nothing happens)
  5. Hit Ctrl+Shift+V (Nothing happens)
  6. Look at the clipboard manually w/ Meta+V
  7. Notice that instead of a typical screenshot, it also says the word “screenshot” on top of it, as well as a +1 symbol suggesting something extra has been copied

The issue occurs in Dolphin as well. Here is the journalctl message:
Data set on unsupported clipboard mode. QMimeData object will be deleted.

Talked to Claude which suggested:

that while the content is being copied to the clipboard (hence the preview), applications might not be able to paste it correctly. This is a known Wayland clipboard issue with KDE Plasma, specifically related to how clipboard data is being transferred between applications.

The “Data set on unsupported clipboard mode” error is likely because gwenview (and possibly Dolphin when copying images) is trying to set data on both the selection and clipboard modes simultaneously, which doesn’t work the same way on Wayland as it does on X11.

It suggested using a middle click instead of ctrl+V to paste between apps and that is working in the interim.

Leaving this open in case someone has a more definitive answer before I close it out.

ksnip’s copy abilities are working and that has become a part of my workflow when editing files and pasting them in Obsidian. I will use that instead.
