It could be inversion too, but it would probably manifest itself on higher brightness, I could only spot it clearly when saturation of color was below 40%. Also if you look at examples of browsing the real webpage the parts that flicker are mostly on edges of fonts, dark areas, which also suggests some kind of dithering to get better colors. Anyway I’ll have to check how lagom’s test looks under microscope - that’s a good idea 🙂
Regarding Quantum - I haven’t checked it, I hope the difference between standard browser and Quantum can be observed with my gear, but if it’s subtle I doubt that it will get caught. Could you share any specific websites that are worse on Quantum? Or recommend another browser that is better to test it against.
Speaking of software - I looked at the gray color of the new GMail which is also cursed, but haven’t spotted anything different so far - probably it’s a mix of gray text on gray background, awkward Chrome font rendering and general usage of gray colors which are composed of all R, G, B in different shades which makes flickering more likely. Reddit under chrome is another interesting case of how bad a website can look now.
I’ll also check if Ditherig changes anything on different machines, but I couldn’t spot the difference with bare eye on my newer laptops, probably it doesn’t support modern graphic cards from Intel. I’ve only seen it making a change on an older HP DV6 (bars instead of gradient), but this laptop is close to impossible to be put under this microscope (broken charging port requires it to be positioned carefully to operate). I don’t use Linux on a daily basis so I’ll probably check it one day, but not soon. It would be more interesting if there was a known distribution / version that is helping in some cases. It could lead to software, not hardware solutions which would be better for us.
By the way - does anyone have access to a microscope (any semi-professional with zoom around 50-60x should be enough) and a camera that is better than one on the phone? I may be limited with this stuff, however I’m not sure what factor is the most important for camera. I hoped for better results with Iphone, but it proved to see less flicker, probably due to some aggregating / averaging algorithms used to make videos more fluid.
