>In case of multi-display surface Wayland can use 'unknown' subpixel ordering.
Do you know if commonly available font renderers will automatically disable subpixel rendering in the case that they don't know the order of the subpixels?
(Not that there's any particular reason you should know, bu this is the first time I've even seen anyone bring up this issue in Wayland discussion which kind of implies you've at least thought about it more than most.)
>Uhm. It has this knowledge in 99% of cases.
But not in X, you previously said?
>And personally I prefer occasionally looking at blurred screenshots rather than looking at blurred text _all_ the time.
I'm not quite clear on that - subpixel rendering is an attempt to make text closer to its theoretically correct shape in exchange for making it less sharp, so I can't see how it could possibly make text *less* blurred than without it.
The entire theoretical basis of subpixel rendering is flawed because it relies on the fact that the colour perception of the eye is less accurate than its ability to discern the intensity. To rephrase that: your eye can discern the improved shape while not noticing the colour change.
This is true to an extent, but in the centre of the eye the colour perception is good enough that in practice there's visible colour fringing in subpixel rendered text unless you either have a very high-dpi display, or you're sitting miles away. I know a lot of people don't mind that and find the trade-off worthwhile, but I most definitely am not among them.
