Any ideias why https://colmeio.com/config takes less the a second to render in Android/Windows using V8 and it takes 20 seconds on Safari WebKit to render. Also the user interaction with the webcomponents are ridiculously laggy on Safari… I may be silly but I cannot figure it out why such difference in performance and I am so frustrated as I took 2 years to develop this PWA which only works properly on non Safari Browsers…

I have tryed to remove all 3D optimizations and will-change properties. It did not make any difference. I think this rendering problem is due to heavily nested components and also some inserAdjacentHTML of my JavaScript chuncks on demand but what catches me is why does my app runs flawlessly on Android/Windows V8 and terribly on Safari WebKit?
