I will add that on my machine (Ubuntu 16.04.1) increases in CPU usage get triggered also by changes in the network connectivity. For example, if the WiFi connection drops and Skype tries to connect, Plasma goes immediately to 100%. Killing Skype reduces the CPU usage to 15-30%, but it stays around that for a while.
Same thing when using Dolphin to copy large files from the internal SSD hardisk to USB thumbdrives. (I'm sure it's a fixable, and it will indeed be fixed in time for the announcement of KDE 6, which will bring all kinds of new and exciting bugs together with some nasty and unavoidable new features) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1597792 Title: plasmashell high CPU usage (100%+) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plasma-workspace/+bug/1597792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
