The iPhone xs’ display is considerably less smooth when scrolling than my iPhone 7 Plus it replaced.
In fact it’s quite horrendous. I see these strange horizontal lines/glitches when I scroll. Particularly noticeable when tracking text as I scroll. I just got this phone and am in love with it but I am really starting to notice this scrolling effect now. That ain’t pretty. It genuinely feels like a step backwards when I focus on the browsing and scrolling experience itself. Which is what takes over your attention when using the phone of course. I don’t notice all the other fancy stuff I just notice that the text is falling apart in front of my eyes. There’s quite noticeable tracing as well. Does this have to do with refresh rate?

There’s something wrong. Very bad refresh rate or frame rate whatever it is

Symptoms described pretty much exactly as how I experience it.
