I was just browsing the net and realized that the CPU temperature is 86C. Then started investigating it and found out that the "seconds" setting was causing the issue. It increases CPU usage to 100%. Reproducible: Always Steps to Reproduce: 1. Place an analog clock on desktop 2. In settings, enable "seconds" 3. Check cpu usage/temperature Actual Results: It is above 80C and cpu usage is too high Expected Results: It should be normal
being the seconds hand animated, probably not really avoidable
It's fine here, maybe it's stressing the CPU if if we end up using mesa as the openGL backend? qdbus org.kde.KWin /KWin org.kde.KWin.supportInformation

thanks.
I can confirm this issue with plasma 5.3 and Intel graphic. Using the "show repaint" in kwin settings show that the whole desktop is refreshed every second (no matter of what vsync option is used), I think that this behaviour is the problem here.
That's meant to happen
Cannot confirm this bug/CPU usage is normal after enabling seconds in KDE neon Developer Edition Unstable Branches: KWin Support Information: The following information should be used when requesting support on e.g. http://forum.kde.org.
