Weird page flicker on macOS 10.15.2 with chrome 79 (latest)
So after encountering a few other websites that caused me some trouble

Like any of the following (and apple.com)


https://obsidian.md/
https://affinity.serif.com/en-us/designer/ipad/
https://www.windowscentral.com/how-determine-graphics-card-windows-10


I was able to fix it by enabling hardware Acceleration 

Go to Chrome > Settings > Advanced > Enable Hardware Acceleration

I opened a chromium bug report https://bugs.chromium.org/p/chromium/issues/detail?id=1094727
