It's kinda interesting that macOS doesn't even care about this problem anymore. When moving or resizing windows on macOS the hardware mouse cursor slightly trails ahead of the window, it's not very noticeable because of the 120Hz refresh rate (meaning the framebuffer surface spends less time waiting for presentation, thus reducing rendering lag) - OTH the lag is still visible, and this sort of minor visual imperfection is quite un-Apple-like (at least for 'old Apple').
It's a bit similar to how high resolution displays make fancy subpixel font rendering tricks obsolete (e.g. high display refresh rates making tricks to hide presentation latency obsolete). Sometimes hardware progress makes complex software solutions obsolete, but usually still with one or another tradeoff.

- account42 2y agoUnfortunately a low of newer displays (especially OLED ones) don't have regular horizontal RGB/BGR layouts anymore. I have seen both vertical subpixel layouts as well as triangle layouts or other funky subpixel arrangements. Even if you configure/update your software to those different subpixel layouts the result is not going to be as good.
