Bug#898338: plasma-workspace: Different components hang, high CPU load
Hi, > I think that means that the kactivities database is broken, you might > want to try moving ~/.local/share/kactivitymanagerd. That seems to fix it. So is this a plasmashell bug, or a KActivity bug, or both, or none? -nik signature.asc Description: PGP signature

Interesting observation: When the panel catches up and does something, it seems to still be stuck somewhere back in time: It froze at 21:52, when I noticed, my wall clock showed 22:12. At 22:17, the panel clock jumped to 21:59, some task switching requests got handled and my sound volume exploded (because some 5-6 minutes back, I used the volume up key). All applications not linked directly to Plasma work absolutely flawlessly and fast. signature.asc Description: PGP signature
