plasmashell cpu usage never goes below 70% on my intel based laptop. I researched this issue and have found many recent posts regarding the same. Weird thing is that I have an AMD based desktop which the same exact desktop settings including plasmoids, taskbar settings, etc and plasmashell stays around 1% usage. It appears that over time, the cpu usage increases as I see it bouncing over 300% after a couple hours use, but can't say for sure as I usually have to reboot it as it becomes so unresponsive. This has been going on for over a month and I was waiting for the kde plasma 5.7 release before posting a bug. Reproducible: Always Steps to Reproduce: 1. use kde 2. run top command and watch as it never falls below 70%. 3. Actual Results: System is very slow and unresponsive. Expected Results: It should be less than 5%, my AMD system never has gone above 2% as I used it as a reference. emerge --info Portage 2.3.0 (python 3.5.1-final-0,

same problem here... have to kill (and restart) it at least twice a day, looks like it also has some serious memleaks interestingly it got even worse with 5.7.0
I switched to the modesetting driver - problem gone :)
That brings up what may be the factor that causes this. My laptop uses the intel video driver where my desktop is nvidia.
Any feedback about whether this is still an issue with Qt 5.6.1/Frameworks 5.26/Plasma 5.7.5 would be appreciated.
This is still an issue for me. I have googled the heck out of this and tried everything I have found with no results. Even disabling composting doesn't help. Plasmashell CPU usage never goes below 70%. My laptop is worthless with this problem as my fans are constantly spinning to keep it cool and the battery drains quickly. My desktop has an nVidia video card and plasmashell runs less that 2% CPU with composting and the same plasmoids. I have a feeling it is an intel video driver issue.
After tonight's KDE Plasma update I did the same thing I have been doing when receiving major KDE Plasma or Frameworks updates: Log in as root Rename my normal user's .kde directory Log out and log in as my normal user This time plasmashell CPU usage is on par with my NVidia desktop system. Reconfigured KDE to my likes and have been beating it up now for about four hours as I wanted to be sure this problem has been solved, and so far it has been running great. Not sure what was done to fix this issue, by for my this problem appears to have been solved.
