Clipping on 'g' on macOS Terminal.app

[stlee42]

Problem description
Using Recursive Mono Linear Static TTF fonts, the bottom of lower case 'g' gets cut off.

Expected behavior
No clipping.

Screenshots

To Reproduce
Steps to reproduce the behavior:

1. Use the font on macOS. (This also happens in apps other than Terminal.app like TextEdit)

Environment (please complete the following information):

• OS: macOS Ventura 13.4 (22F66)
• Browser: N/A
• Fonts: TTF static fonts from ArrowType-Recursive-1.085.zip release

Additional context
As with bug #513, the problem is not present in OTF version, though the line gap is increased, which is not desirable.

Could be a hinting issue.
The bottom of the g is at -250.
The decender setting is -250.
There is no line gap - it is set to 0.
So the OTF is inside the vertical metrics (and macOS may be hinting it to stay there).
The TTF has the same vertical metrics, but the hinting in the font may be pushing the bottom of the character below what the application is displaying.
Could just be the application rendering is in error (or just dumb - to hint-adjust to clipping).

The TTF hinting is done automatically as the fonts are being generated.
It may be possible to modify the settings for that automatic hinting which may affect this issue.
And the font developer may or may not want to mess around with that.
Manual hinting is very complicated and very time consuming - and not likely to happen.
My guess is if the font developer has the time and the inclination to test automating hinting settings/modifications with these particular applications, and assuming that actually "fixes" this issue, then the earliest this would happen is the next release (whenever that may be).

actually, on macOS, the fonts are rendered anti-aliased without hinting.

Bad description on my part.
It is doing its own grid-fitting.

[stlee42]

aren't grid-fitting and hinting the exact same thing? at any rate, macOS does not do it.

also, in my case, it is definitely a clipping issue of line height type, not grid-fitting or hinting issue. If you look at the screen shot, you can see that one of the g's on the second line is not clipped and shows the full form. the clipping is intermittent according to how the line is redrawn as you press enter or backspace.
