Created attachment 97958 [details] The video that describes the bug Basically this bug https://bugs.launchpad.net/ubuntu/+bug/11334 One of the fixes is installing a clipboard manager. However klipper doesn't fix this bug, the clipboard gets empty if the source application is closed so ctrl+v doesn't work anymore and you have to look at klipper history in order to retrieve what you earlier copied. (this doesn't happen with all applications but it does happen) Installing parcellite fixes this bug.
which Qt version are you using and with which applications do you experience the problem?
(In reply to Martin Gräßlin from comment #1) > which Qt version are you using and with which applications do you experience > the problem? Qt version: 5.5.1 I don't experience this problem on any kde application, until now I have experienced it on firefox and codeblocks (which uses wxwidgets)
> I don't experience this problem on any kde application, until now I have > experienced it on firefox and codeblocks (which uses wxwidgets) If I remember correctly Firefox explicitly clears the clipboard before closing. In that way it's not a bug, but a feature (questionable, but not much to do from Klipper's side). Codeblocks I do not know.
From time to time, the copy+paste stops working for me even between KDE components (see the video). It affects apps used for some time (weeks ...), but the computer were not suspended any time ... When new instances of the apps are invoked, copy+paste works on them.
