The problem is greatly reduced or even resolved after having VMware Tools reinstalled. My last comment was not appropriate. The problem still continues on. I have the same behavior on Fedora 24 with KDE Plasma 5.8.6, Frameworks 5.31.0, QT 5.6.2, and VMWare 12.5. There are other reports of this as well: https://forum.manjaro.org/t/plasmashell-kde-high-load-over-my-cpu/8645/5 One commenter at https://superuser.com/questions/1118866/high-load-over-my-cpu-and-high-temperature-when-running-plasmashell had an interesting theory, but I have not yet tested it: > FWIW, we ran into this at work and it turns out it's the vmware tray icon. If you kill the vmware-tray process after you start up the VMs, then everything is fine. There is an option to say that you don't ever want the icon, but that doesn't appear to be honored and VMWare fires it up anyways. CPU usage increases to about 60% on plasmashell, with a significant percentage on the Xorg process and on the VMware process, even with an idle VM. Shutting down VMWare has no affect, but restarting plasma after shutting down VMWare fixes the issue. The display becomes sluggish until plasmashell is restarted. Following on my last comment, I believe I can confirm the issue with vmware and plasmashell, at least on my machine, is related to the vmware-tray process. I started vmware and immediately killed the vmware-tray process on my Fedora host. Since that time, no more CPU issues with plasmashell. I'd like to hear from the OP whether or not that is the case for him also. Now I suspect that vmware is doing something naughty related to the tray... but, I don't believe any program should be able to "break" plasmashell using any tray APIs, no matter what they are. Allowing this is essentially allowing a denial of service attack on plasmashell. Can't reproduce plasmashell process uses normal amount of memory when VMware app is running, tray process uses ~1% of CPU and 1% of RAM (8GB) vmware-workstation 14.1.1-2 Plasma: 5.12.2 Apps: 17.12.2 Frameworks: 5.43.0 Qt: 5.10.1 Kernel: 4.14.25-1-MANJARO OS: Netrunner Rolling Thank you for reporting this issue in KDE software.
