I updated to kde neon 4.12 today and copy paste between wayland and Xwayland applications is broken again. I am using KDE neon user edition Tested: I tried copying and paste between updated konversation and Firefox.
I couldnt find the Xwayland tag.
I am using 2:1.18.4-0ubuntu0.7 amd64 xwayland i typed it manually i hope there isnt any mistakes
Works fine for me.
I had that problem on my old Arch Linux installation running plasma 5.12 beta. Some days ago I did a new installation because boot issues and the problem disappeared. No idea why.
Which config file should I delete then?
I ran these 3 rm in $HOME/.config rm kwinr* rm kcminputrc rm kcmshell5rc I am not sure whether logging out fixed it or removing any of those files fixed it. copy paste between xwayland and wayland is working again
Marking it as resolved. Maybe I should had kept those config files in hindsight
