Rows of text seem clipped at certain font sizes on Catalina

[twk]

Running 8.1.950 on Catalina, when I start MacVim, some lowercase letters are getting clipped:

If I adjust the font size and then adjust it back, things are rendered correctly:

This started as soon as I upgraded to Catalina -- Mojave was fine. My font settings are English/Menlo/Regular/11

I will need to see if I can repro this under the new Xcode. Otherwise could be tricky as I don't have a beta Catalina install with me.

Happens for me after upgrading to catalina, but, only with Core Text renderer enabled.

With Core Text renderer disabled things are actually considerably worse.

I'd wait for first public beta. Before that point macOS is not really usable at all

[adamjacobmuller]

Aside from the MacVim issue my workflow is fine and I've just been running vim instead.

[eirnym]

I'm really surprised to read it! This release will be the first one with relatively stable betas, since it wasn't a case since macOS 10.7 Beta 1

[eirnym]

Public Beta is out…

[eirnym]

It's interesting, I can reproduce it with

guifont=Menlo-Regular:h11, but not with guifont=Fira\ Code\ Light:h12

This is a duplicate of #883.

Oh, @eirnym, it's because the comparison sees that the new font Menlo-Regular:h11 is the same as the default font initialized by -[MMCoreTextView initWithFrame:] and skip rest of the initialization:

if (!(newFont && font != newFont))
    return;

That's why in this case fontDescent is still properly initialized.

(lldb) p font
(NSCTFont *) $0 = 0x0000000101c233e0
(lldb) p newFont
(NSCTFont *) $1 = 0x0000000101c233e0
(lldb) po font
"Menlo-Regular 11.00 pt. P [] (0x101c28300) fobj=0x101c233e0, spc=6.62"

(lldb) po newFont
"Menlo-Regular 11.00 pt. P [] (0x101a00860) fobj=0x101c233e0, spc=6.62"

[eirnym]

I've tried it after Fira Code, to guarantee that it's a different one

[jjgod]

That's why you are not hitting the problem with Fira Code.

[eirnym]

and what's about Menlo?

I've set Fira Code first, then Menlo, and issue still exists. This doesn't neglect your issue on fontDescent, though. Probably, in macOS Catalina this parameter becomes more valuable to set if it's not.

[jjgod]

How exactly did you do that? Did you execute multiple set guifont command?
