Hello there,
I just want to notify SublimeText developers about this bug.
When I came across it, I was configuring SublimeText to use 'PragmataPro Mono` font family instead of ‘PragmataPro’. By that time I had already uninstalled all PragmataPro font versions I had earlier and installed only ‘PragmataPro Mono’. When I launched SublimeText with old preferences, containing “font_face”: “PragmataPro”, it consumed 1 CPU core and did not show any windows. After I changed the preference to “font_face”: “PragmataPro Mono” (using another editor), killed the running SublimeText instance and launched it again, everything worked fine.
I am still able to reproduce this bug, but only with “PragmataPro” and “PragmataPro Mono” font families. Reproduction steps:
- Exit running instances Sublime, if any.
- Locate Packages\User\Preferences.sublime-settings file and open it with any other editor.
- Change “font_face” setting from “PragmataPro Mono” to “PragmataPro”
- Run SublimeText
Expected behavior: SublimeText should start and use some fallback font.
Observed behavor: SublimeText instance consumes 1 CPU core and does not display any windows.
Probably one has to have “PragmataPro Mono” font installed to reproduce this problem.
Version info:

Windows 10 x64.
Best regards,
Evgeny
