OBSERVED RESULT
On an i7-8665U, CPU run at full speed (4.20GHz turbo boost) for 10 seconds
EXPECTED RESULT
CPU stay cool (~700MHz)

ADDITIONAL INFORMATION
I have solved the problem for myself using the following workaround:

so I don't know if it is a bug from kturtle or from QT, I don't really
understanding c++...
Happy Hacking.
