I regularly use wl-copy and wl-paste. Normally they work without any user intervention. After upgrading to Plasma 6.5.0 yesterday on Arch Linux , instead of pasting the text at the prompt an icpn appears in the taskbar which requires clicking.
This is actually a bug in wl-paste. It’s not working properly with the Wayland activation protocol. Prior to Plasma 6.5, this issue was masked by KWin’s Focus Stealing Prevention setting not working. In 6.5 it does work, exposing the issue.
You can try setting it to a lower level. It’s working fine for me with the setting set to “low”.
Thank you. I actually replaced wl-paste with wl-paste-rs and it seems to do the trick.
