Bug 344040

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?

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:
