I have the same problem. I also noticed in the journal the following errors when I attempt to capture a screenshot:

Just discovered this is likely a duplicate or similar issue to #727?

Getting same issue on KDE plasma 6.0.2 with ksnip 1.10.1

[32bitx64bit]

Issue can be fixed by enabling Force generic wayland under the image grabber settings.

Ksnip still doesn't have the ability to do much other than capturing full screen on KDE. Hopefully this gets resolved.

Same error on KDE plasma 6.0.4 - wayland on flatpak version.
