This seems to be a driver problem then, nothing we can't solve in KScreen.
Please file a bug against your graphics driver.

Sorry I can't help much with this issue.

Yes, with xrandr also occurs when i set 59Hz or 60Hz. With 30Hz is ok.
Look for pclk value, is this not too high value for this 3840x2160@60?

Thanks for the report, Tomasz!

Could you check if this behavior also occurs if you use the xrandr tool to set
up your screens?
