I have recently tried several fonts - "IBM Plex Mono", "Intel One Mono" & "Source Code Pro" (on Windows 11), but display quality are pretty bad. However, "Fira Code", "Red Hat Mono" & "Noto Sans Mono" are displayed pretty well, though not as good as in VSCode. What am I missing - font rendering? Thanks.

Not sure if this has to do with OTF vs TTF format. Will test and report out.

Installed TTF fonts, replaced OTF fonts. Now, Textadept looks great again. 👍

May be the remaining question is how to better support OTF format, as OTF is supposed to be richer?

Textadept's GUI toolkit (Qt or GTK) handles the font rendering. GTK uses Pango. I don't know what Qt uses. Perhaps their OTF font support is a bit lacking compared to TTF.

On Linux (Debian Sid), the font quality is fantastic despite using OTF.
