Well, shoot. Now I remember why I required Pillow >=8.2. You get a mysterious segfault with earlier versions. The problem was fixed in Pillow 8.2.
See https://github.com/python-pillow/Pillow/issues/3066 However, there is a workaround, provided no one is trying to use a font that requires a vertical layout. I think we're safe there. v5.0.0a20 uses the workaround. On Tue, Feb 21, 2023 at 1:01 PM Vince Skahan <[email protected]> wrote: > This one might be a pi oddity.
