Yep. I tested it - A4Tech refresh rate is 500Hz. it's insane :)
ordinary mouse has 125Hz.  No surprise that throttle takes place when i'm using
this mouse.
So Konsole just tried to draw all frames per second.

Don't bother. Everything is fine. And i use ordinary mouse now, which
ironically gives smother result )
