Can't paste content copied from Krita in Plasma 6.5.2

Hi, I’ve been using Krita and Plasma for more than a year now and one thing that I really liked about it is that you can select something in Krita and then paste it in any path in Plasma, it really helped me to work faster on designs and other stuff.

After updating to Plasma 6.5.2 in Fedora 43, Plasma actually copies the content of whatever I copy from Krita, but after pasting it, it don’t paste anything. I tried checking journalctl to see if there’s an error or something, but it outputs nothing.

I also thought that it might be a bug caused by the version of Krita that Fedora use, because it is a little outdated, so I tried the Flatpak version of Krita and still nothing.

Not only that, but I don’t know if this is a bug or a new intentional behavior that I never heard about, but is there a way to solve this issue?

Cannot reproduce with Krita to Krita or Krita to KolourPaint

I also tested it, and it works with Krita to other programs, even with Firefox, but not with Dolphin.

Here’s a video reproducing this issue, all packages are up-to-date on Fedora 43:

As an update, other people are also experiencing this same behavior with Spectacle and other programs
