That's 50% of one core of your quad core machine, effectively just about 10% of your CPU. Handling more screens is not free, so slightly increased CPU usage during more intensive screen changes is the price - normally you would not even notice because it would have been used in kernel space, in our case it's a process in userspace which you can monitor.

Can you record a video showing the mouse tails, low responsiveness and the problem with refreshes? Is the laptop lid closed by any chance; if yes, does it get better if you keep it open?

Cheers,
