Very slow page build and scrolling
The first example of hanging and slow and jerky scrolling is on this very forum page but the other is at http://rt.com which opens fine but gets super slow if you click on a story.
groingo - I just checked rt.com and I cannot duplicate the scrolling problem. I loaded their home page, clicked on several of their stories (some very interesting - a neat site) and scrolled top to bottom. I have 16 tabs open right now.
What version of Vivaldi are you using and what is your operating system?
I am using Vivaldi 22.214.171.124 on Win 7. I have 16 gb of ram, but the meter with Vivaldi and seven other programs loaded shows that I am only using 26%. Also, I have six different Vivaldi threads open at this time and I am not experiencing any problems viewing or navigating on any of the open sites.
I've tried visiting that site a couple times since you first posted, and even with my piddly 2GB RAM, 32MB on-board graphics 32-bit Win7 system (Vivaldi v126.96.36.199 with no extensions) I can't replicate the problems as you describe them.
It seems like there is a lot loading on each page at the site, but it mostly seems to load very quickly. The one thing I do notice on most pages I visit on the site is that I often get a brief (maybe 3-8 seconds) hang after it appears the page has mostly loaded, and maybe this is related to what you're describing. (?)
With all that said, I usually have 4-6 Vivaldi forum tabs open, and I frequently find the forum response to be very sluggish, much more than it seems like it should be when going forward or back in the tab history, and especially when submitting a forum post.

RT behaves similar with most browsers but Vivaldi does stand out, I agree there seems to be a lot going on in the background of RT.
Will check my GPU and CPU use.
