Horizontal lines appear to be wavy when scrolling on rotated IPS monitor

1

I am connecting an Acer (CB271HU bmidprx 27” IPS 2K) monitor connected via DisplayPort to my 13'' 2017 MBP (graphics card: Intel Iris Plus Graphics 640 1536 MB). When I turn the monitor in portrait (90deg rotation), I notice lines don't update at the same rate horizontally. They appear to be wavy when I scroll up and down. I recorded the screen when I scroll through a picture here. It appears that the left half of the rotated screen is lagging behind the right half. Is this normal or how should I fix this?

And your question is? Also, you may want to advise the OS. – davidgo – 2019-03-30T17:04:46.793
