I'm running: - openSUSE Tumbleweed up to date - Intel Sandy Bridge with Nvidia Optimus which should be disabled In my case the primary reason for the high CPU is having FolderView widgets on the desktop. The bug is definitely reproducible and consistent. I use a desktop with a "Desktop Containment" layout. When the desktop is bare and has no FolderView widgets, CPU usage is normal. Add two or more (one works too, but the results are not as dramatic) FolderViews and restart the system, not just X! After logging back in, CPU usage for plasmashell is +50%, but may be as high as 100%. Remove the FolderViews and restart, CPU usage goes back to normal. This started happening sometime in June 2017 and may be related to Qt 5.9. I don't keep very close track of changes so I cannot be sure. If you tell me how to use strace on plasmashell I'll post traces. I don't have much experience with it. Thanks. -- You are receiving this mail because: You are on the CC list for the bug.
