I am witnessing weird Safari experiences with Intel down here as well

My MacBook air 2010 ElCapitan Safari 10 or 11 was not launching twitter, espN, OSXdaily and other sites
except this one just last week, these sites were active in Jan 23. I also turned off the AdBlockr which did not help.
To remedy this is was a leap to sierra were everything is working and better with Safari12.1.2
even peacock TV works kinda great, slow to launch but steady stream.

but I'm experiencing video not showing on the Mac Mini '12 i7 Catalina were peacock TV does not show video,
only sound and the graphics. I even rebooted, reset PRAM and cleared caché and History,
I did tweet them and they said their site works with 12.1.2 and on, which is true.

Seems to me our older Macs and OS's are wading out. could be our graphics cards are not up to par.
so what am i going to do? What else, buy a new SSD for the 2010 MacBook Air!
Since I need a 4th power adaptor for this MacBook, which is sharing the 2012 MBPro' one.

everything is excellent on the MacBook Air M1 which is resting now as i am tying this on the 2010MBA.

hope this helped in some way.
 
Still no problems here with Mojave on my 2014 Mini or Monterey on a 2018 Mini. The 2014 machine is primarily a media server, the only websites I regularly use are streaming with Sling and SiriusXM, but they work fine.

For me, Safari (on Mojave) is getting back to normal.
What helped somewhat is ... I was using something called "AppPolice" (which can be used to limit CPU activity on apps and processes).

Although it never seemed to interfere with Safari previously, I quit AppPolice and it seemed to help Safari somewhat. Perhaps a "behind the scenes" process needed more power to get its work done at Safari launch moments...

For me, Safari has opened in one bounce for years, but in the last week, it now always takes two bounces to open.
