I’m not sure. If it’s not happening to all devices, then it’s likely hardware. OLED is a new technology to Apple so support couldn’t confidently say whether this was an actual issue or expected with OLED.
I’ve also had this blue glitch issue when scrolling with low brightness and nightshift. Raised it with support as I couldn’t replicate the issue on a friends X. They’ve taken a capture data and passed to engineering - hopefully will hear back tomorrow, but have a feeling it’s going to be a replacement device :/
Update on this is
Had the device swapped out for a new one - exact same issue occurs. Looks like this is an issue with the OLED screen.
I found this test to show the blur \ trail that occurs on my iPhone X display. This tests with a single pixel line but it demonstrates what essentially happens with text:

On my iPhone 6S and my 2016 MacBook Pro I only see a single line going across the screen with a minimal amount of blur, but on my iPhone X I see 3 lines when they only should be one. Does anyone else see the same? At the end of the day it just proves that the screen isn't refreshing properly or at least it appears that way because of the PWM with these OLED displays.
Does anyone else notice a slight ghosting effect / lag while scrolling on the iPhone X? I’m not sure if I have a bad panel but when I scroll through text (e.g. the settings window or in Safari) even at a moderate speed the text is blurred. Compared to my iPhone 6S it’s pretty bad.
Has anyone else noticed this? Does it work well on some and not others?

About 8 lines .. geez.iPhone 8 seeing multiple lines with that pixel test.
I’m lucky as I only see one line. That is not to say that your screen is defective or mine is better, it simply indicates that I am not as sensitive to the phenomenon.
I respectfully disagree with that statement. As you say if it is happening for a fact and a known issue, yet only some see it and others don't then it is all about sensitivity to it or not. Very normal with these kinds of display technologies.If you only see one line then a lot of people on this thread must have defective panels. The ghosting issue is not a “phenomenon” as you describe it. It is happening for a fact and ghosting is a known issue in panels, whether that be in LCD or OLED technology in televisions or phones. It has nothing to do with people being sensitive to it or not.
When ghosting occurs you will see it regardless of whether you are sensitive to it or not.

It is not your eyesight, it's your brain and how it interprets it. Yours might be better at mine that it can identify multiple lines at that refresh rate. Or perhaps mine is better at processing it to turn it to one line. Who knows - one thing I'm confident about is that the displays are the same. It is highly unlikely to have such variation for such small panels.Let me put it another way, my eyesight is fine, but I see multiple lines on my phone but you only see one line.
We both have the same phone. That means the panel in my phone isn’t of the same quality as the panel in your phone, because mine is displaying 3 lines whereas yours is displaying one line.
Other people have said their phones are displaying up to 8 lines, that’s heavy ghosting, whereas your phone is displaying 1 line.
Therefore how can you say that is down to a persons sensitivity to ghosting, when clearly the panel should be only displaying a single line like it does on your phone, but it isn’t on other people’s phone.
Google the term ghosting, it is a known issue, you don’t just see ghosting because you are sensitive to it or not, you see it because the refresh rate on a display is not high enough to display fast moving objects.
