Here is another video: rendering of fonts on W10/Macbook Pro in different browsers: Chrome, Edge, Firefox in current versions (I'll downgrade Firefox to see if it differs later).
https://vimeo.com/294862076
I ran custom script that scrolled through sets of "S" letters (since it has most curves, so most potential antialiasing would happen) in different fonts, boldness levels, with antialiasing set to on / off, etc.
Results may not look groundbreaking, but you should clearly see dithering on the edges where antialiasing (i.e. shading on subpixel level) happens. Actually this is not so big as I saw before on some pages - probably there are worse fonts than the standard ones I used (Courier, Times New Roman, Arial, Verdana, etc.). Also worth noting is the fact that this screen is retina, i.e. pixels are really small, so the same fonts should use more dithering on screens with lower resolution.
Next test I'll be preparing is running the same "S" letters in different shades of gray. I've seen that lots of sites (even Ledstrain) use some deep gray instead of black for the color of their main font. So it's likely to dither, although it seems to be black.
I think we may start sharing these videos with more experienced guys (i.e. tech, industry contacts) as @martin suggested since further tests will not be likely to reveal more details, the only big step may be finding a setup (OS, driver) that doesn't dither on the screen that flickers usually. I'll be testing early W10 installation soon, but I don't have high hopes.
