Light text on dark background starts flickering when scroll if u got enable hidpi

Hi, my setup is macbook pro m1 with monitor Q27G2E/BK (connected with displayPort -> usb-c, also tested with Hdmi cable).
When I turn on hidpi resolution, light text on dark background starts flickering when scrolling vertical and horizontal axis. But text on light background looks fine.

Do you have a video of the phenomenon? With heavy supersampling via HiDPI it is possible that finer parts of the font become visible/invisible during scrolling as some pixels gets shown/hidden depending on whether the scaling algorithm makes them appear on the much less physical pixels, which might end up depending on whether they are on odd/even logical pixels.

This appears to be a display panel g2g lag issue - prevalent on many IPS panels. If the panel has some kind of panel/pixel response "overdrive" mode, that might help.
