It's happens only when in X11. In Wayland it seems to be OK.
Comment 2 firewalker 2024-03-11 09:25:29 UTC 
It must be related with the Force font DPI option in System Settings -> Text & Fonts.

If this option is checked both in X11 and in Wayland, the problem occurs.  

Before KDE 6, it was OK.

This looks like a duplicate of my bug, but I don't have force DPI checked in system settings. 

I do have custom settings for display in X11 (which is part of the reason I don't have force DPI set for KDE):

```
Section "OutputClass"
Identifier "cfr eDP-1"
Driver "modesetting"
Option "Monitor-eDP-1" "cfr DPI"
EndSection

Section "Monitor"
Identifier "cfr DPI"
DisplaySize 277 156
EndSection
```

I note that this worked fine prior to KDE6.

The problem also occurs if the image is saved to file rather than pasted.

Do you need any additional information? This bug is not critical, but it is highly annoying and I'd be glad to provide more information if I can.
