Hi so am using Cinnamon(Not Linux Mint),i kinda liked Kdes features but i found it buggy so i had to give up kipper and switch to cinnamon,I tried Diodon(too buggy,a little old and doesnt store images) and Gpaste (doesnt store images,and only store clipboard while open) thanks.
No idea why you consider KDE buggy. Maybe the distro you’ve used ships old version or the build is low quality, maybe it’s the matter of using Wayland vs X11 and outdated NVIDIA drivers? For me, the current Plasma 6.2 is rock solid on multiple machines.
Other than that, for try this https://github.com/diodon-dev/diodon Or this https://github.com/hluk/CopyQ
Found copyq really nice, kde on my distro is 6.2 it was wayy worse before kde 6 trust me + kde looks a little worse then any desktop (even its lightweight brother lxqt looks nicer).
