libreoffice takes around 40 seconds to start on my core i7 laptop. Judging by
ktrace, what it does is reading iosevka fonts. This fragment:
```

```
Workaround to fix the slow startup is thus to remove iosevka font.
I think it should be reported upstream, just leaving it here for searchability
and for the workaround.
