Each time I have seen this, I initially thought it was plasma. In my case, at least, plasma was showing as the culprit, but in fact it was the nsplugin viewer for flash causing the hiccup. I kill the plugin viewer for flash, and plasma would start behaving.
Can you test this and see if there is a nsplugin instance running at the time of the problme, and kill it and see if it fixes it? For me it does. -- kdeinit4: plasma-desktop takes 60-90% of CPU https://bugs.launchpad.net/bugs/419054 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-workspace in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
