For me, being old time user, (ab)using any subpixel layouts for text rendering and antialiasing is counterproductive and (especially with current pixel densities, but also in general) introduces much more issues that it actually ever solved
“Whole pixel/grayscale antialiasing” should be enough and then specialized display controller would handle the rest
Agreed, but layouts such as Pentile don't actually have all three subpixel components in a logical pixel, so you'll still get artifacts even with grayscale AA. You can compensate for this by masking those missing components.
surprising info, I thought this was supposed to be the part about "display controller taking care of any additional issues", thanks for link with details, will read it with interest
