Klipper fails to paste big images

Help

(making sure I’m not just doing something wrong before making a (possibly duplicate) bug report)

When I make a rectangular screenshot of a portion of my screen, Klipper doesn’t have any issues letting me paste the resulting image. However, if I make a full-screen-size screenshot (or do a “Capture Entire Desktop“ action), I can’t paste the image, but I can see it appearing in the clipboard history. As a workaround, I can open Klipper (in the system tray or with Meta+V), select any other entry and then back to the screenshot I want to paste, then it pastes it.

Some screenshots of my configuration:

What’s your screen resolution?

My screen resolution is 2560x1440.

I’ve just tried and now it fails with rectangular full-screen-size selection only in 5% of attempts… But with a “Capture Entire Desktop“ action it’s more likely to fail (I’d say 40% of attempts to paste the screenshot fail).

This is not exactly a critical problem, but a very annoying one nevertheless.
