To do it properly, you need a bit more than just `backdrop-filter: blur(8px)`; see <https://www.joshwcomeau.com/css/backdrop-filter/#the-issue-2> for a clear demonstration of the problem, and the rest of that article for the solution (with further relevant details and discussion in <https://news.ycombinator.com/item?id=42302907>; in this particular case, the backdrop blur needs to be able to access 15px more of the backdrop than it can unless you go out of your way to give it that).
After the events of 9/11, the skies were empty for a few days
> During the three-day commercial flight hiatus, when the artificial clouds known as contrails all but disappeared, the variations in high and low temperatures increased by 1.1 degrees Celsius (2 degrees Fahrenheit) each day, said meteorological researchers.
I was issued the 16" last gen Intel MacBook pro at last job (new job I'm back on whatever I want) and it was a seriously underwhelming experience for 3K's worth of hardware, screen was good, touchpad was sublime -everything else was crap.
Battery life was mediocre (worse still if you actually use it), it got ridiculously hot under load, the fans where really loud and pitched at a frequency it was hard to ignore - I'd have put it down to a bad unit but everyone else with the same model had the same issues.
It was fine but for double good thinkpad money it wasn't fine enough.
I was glad to hand it back, new place doesn't care what I run so I'm back on Fedora on a fast desktop and I'm happy again, I still have a work issued macbook pro but it sits on a shelf behind me until I need to test something.
The most mind-blowing part of the 16-inch MacBook Pros are really the speakers, which are really nice for laptop speakers. However, that's also quite sad that it's the highlight.
And you'll see you just needs a single CSS property `backdrop-filter: blur(8px);` to achieve this effect nowadays =)
