Copy-paste seems to forget the cut buffer if the application being cut from is closed. I am running Kubuntu 14.10 plasma 5 test ISO. I have a System 2011 vintage System 76 with a nvidia M560 graphics card, and the proprietary driver. Reproducible: Always Steps to Reproduce: 1. Open an application, for example firefox. Go to a page, select some text and hit ^C 2. Open kate (or anything else) and hit ^V. The copied text will paste in. 3. Close firefox. 4. Go back to kate and hit ^V. Nothing will paste. Note that the original selected text will show in Klipper and can be selected if you first select one of the other choices.
I am not sure if this is bug originates from Plasma 5 components / klipper but yes I can reproduce this
Thanks for your quick attention. I wasn't sure where to file this, so I put it in plasmashell. My guess is that it is actually not klipper because klipper actually seems to set the text properly when you change your choice.
