Razer Blade 17 super slow after sleep / stand-by

So, I have a Razer Blade 17 - RZ09-0423QED3-R3E1. Everything is fine, except since perhaps a couple of weeks ago, almost every time I wake it from sleep / closing the lid, it is terribly slow. Anything from browsing internet to accessing files; every click has a delay, so I have to restart the laptop & then it's back to normal. It's not the waking itself that is slow, that's almost instant, but the system stays laggy after. All updates on windows or razer's end are done.
