Make a custom resolution:
I noticed I could see the lines @ 120hz and worse @ 144hz. The screen also has a standard 119hz mode though. I tested that and the lines were completely gone (verified by me, my girlfriend and another friend who can easily spot them). So I went into Nvidia control panel (you can also use Custom Resolution Utility, it's free!) and made a custom resolution.
The only thing I did was set 144hz mode, but change the actual refresh to 143 hz (you have to choose a decimal value between 143 and 144, I went with 143.00hz) and guess what... it's gone! I don't know if it transfers to games but it's a very obvious difference and I thought perhaps you (or others) could try this as well if you've got monitors with this 'issue'. I got the idea from what I noticed at 119hz vs 120 and read that some ASUS models could get rid of the issue by making custom resolutions as well.
This fixes all 'movement' of the screen including those lines whilst it doesn't affect image quality in windows at all.
Please let me know if I'm on to something here if you've got a monitor with visible lines lying around!
EDIT2: For some reason this only works with Blur Reduction off... If I turn it on, the lines are gone at 144hz, but visible at 143, tested 10+ times... Really strange, but true for some reason. Seems to have to do with the fact that Blur Reduction usually only works at 120 or 144hz, by turning it on through FPS1-mode it forces it on 143, causing visible lines.

Regarding the Horizontal + moving scanlines from bottom to top. Only visible @ uniform mid-bright image content like grey and when looking very close to it (from a distance of approximately 30cm). I wouldn't say necessarily that this is a "real" disadvantage. It's by far not that visible like the scanlines from the CHG70 or the PG348Q for example. It also isn't possible to capture this on camera. These scanlines are not as usual "scanlines", they are like vertical thin "darker" bars traveling from bottom to top.
