Studio UI responsiveness in Chrome

For some reason, studio UI in Chrome is not that responsive. Especially in screen designer, I regularly wait 1-2 second(s) for a clic to have effect.
And this is after having deactivated most of my extensions (especially ublock & ghostery which clearly slows down the train).
GPU acceleration is activated.
Not sure if I’m the only one, in the meantime I switched to Firefox and this is much better.

This is strange - Studio usually works on Chrome much faster than on Firefox. All my colleagues use Chrome.
What is your Chrome and OS version?

Windows 7 ultimate sp1
Chrome : interesting, it just updated itself to Version 51.0.2704.106 m (was something) and restarted. Now it is much much better.
Either the update did it. Or the restart did it : I have 4 virtual desktops with dozens of chrome tabs open permanently and the pc is always on. Or both.
Anyway, issue closed !
