I can confirm that Enpass is clearing any copied content - even when it's locked and content is totally not related with Enpass (e.g. copied from kwrite). It cleans both text and image entries. I'm using recent kubuntu: It's kubuntu desktop environment, I'm using klipper (not sure if it have any impact but may be worth mentioning). When I disable auto clibpboard cleanup feature in Enpass clipboard works fine. Also, I see that Enpass is reacting to clipboard changes - I've copied some text from kwrite while running strace on Enpass process: First two lines appeared when I copied the text to clipboard. The last line was produced when clipboard was cleared. I did not touch Enpass in meantime at all.
