I think that is why i wrote "Maybe its not always 60fps". I can feel it.
I used Kwin Show Fps plugin. fps if quite high ~50. But there are red spikes on
the graph that appears only when i scroll konsole. It represents frame draw
time. It become red in 20ms-50ms range - if i read kwin sources correctly.
Is it possible to throttle for 15ms and not more?</pre>
