--- Comment #4 from Enrico Tagliavini <enrico.tagliav...@gmail.com> --- As suggested by Rex I tried the Plasma 5.8.3 packages from the Fedora KDE unstable copr repository (which is what will become the official Fedora packages) https://copr.fedorainfracloud.org/coprs/g/kdesig/plasma-5-unstable/ Problem still exists unfortunately. I have the impression using programs like virt-manager and krdc makes the problem easier to reproduce. I frequently have a CentOS 7 VM running and open in virt-manager and I use a desktop on it. I also use krdc quite frequently to connect to remote Windows systems right after closing KRDC I noticed plasmashell process eating between 50 and 100% of one core (it started before I closed KRDC I noticed the environment to become less and less responsive). To be clear: I think krdc and virt-manager are making the issue appear faster, they are not the only trigger -- You are receiving this mail because: You are watching all bug changes.
