spectacle clipboard pasting not working correctly in kubuntu (seems to be size dependent)

submitted by

i am been using spectacle to take screenshots but in a way where i get the rectangle selection right away and afterwards the image gets immediately sent to the clipboard.
but since the last update to Kubuntu 26.04 LTS i am having trouble pasting the picture. it is there in the clipboard history, i can see it but it doesn’t paste. i have to select another image from the history first and then the screenshot i just took again to be able to paste it. this behavior is only present with pictures, the clipboard functions normally with text.
is there a way to fix this?

edit: i just did some testing as i had the feeling it has something to do with the size of my selection. when i take only a smaller selection the pasting works without issues but if i use a larger selection it doesn’t paste again without the workaround mentioned above. i use a 1440p display and smaller is maybe 1/10th of the screen and larger is maybe 1/4th of the screen.

edit2: today i got an update for spectacle from 4.6.6.4 to 4.6.6.5 and it seems to have fixed the issue

Did you upgrade or is it a new install?

I thought upgrades weren’t officially available until August.

not a fresh install, it offered me the upgrade a couple of weeks ago through discover

I’ve generally heard 26.04 isn’t doing too hot right now, and I always thought there wasn’t an officially supported upgrade path until things are more stable in the new release, but maybe that’s Ubuntu proper and not Kubuntu.

I haven’t gotten a notice to upgrade, however. Also on Kubuntu 24.04.

must’ve been a small window where it notified me then, idk. distrowatch has the release date as 2026-04-23 but i might’ve upgraded in early may as i am not super keen to update when i have a stable system.
i have no issues other than spectacle.

My issues with spectacle is time dependent. The clipboard automatically clears the image after 20 seconds and there doesnt seem to be a way tp configure that
