Gsconnect chrome/chromium extension

Noticed that scrolling in Chromium was extremely slow, some delay each scroll on the touch pad… tried again this morning - same issue…
So I purged kodi (which I’d installed yesterday), updated and rebooted… still issues… turned off hardware acceleration and relaunched Chromium - marginal improvement, if any… chewing up up to 100%+ CPU cycles… What gives?

So - I look at my extensions - try turning off some… soon as I disabled gsconnect - everything back to normal! Turned all the others back on that I’d disabled - and still good…

Warning : gsconnect Chrome/Chromium extension is a performance hog!
Perhaps it’s 'cause I don’t actually have gsconnect installed and paired with my phone?
