instead. (In reply to Nikolaus Waxweiler from comment #8)
Do you mean subpixel rendering?
Right, sorry. ftview does its own thing, so I started simply comparing GTK
applications. The setting I was referring to here is "Antialiasing: Subpixel"
in GNOME Tweaks.
This is interesting. In ftview from that build, If I enable normal
anti-aliasing (A) and forced autohinting (f) and switch to subpixel
rendering (C) and forced autohinting, some glyphs seems to glitch by being a
pixel or so wider at 16px (e.g. i, j, doubles quotes). Aside from that,
nothing changes significantly?
ftview's rendering doesn't seem to be representative of what GTK does, so it
might not be the best test case. Your image does show a bit of the tendencies
though as there are a lot of single pixel wide stems in the lower left example.
(and the glitch is mentioned on bug 1035486 comment #36)
In the newest ftview from git, I can't seem to enable full
autohinting with
subpixel rendering.
Isn't that the problem though? Neither ftview nor GTK is able to get that mode
fully working.
(In reply to Nikolaus Waxweiler from comment #10)
Going on a limb here, have you tried enabling warping? Only available
in
slight autohinting mode.
It seems to have some effect, but it doesn't even compensate for the extra blur
caused by going from full hinting to slight.
