New (since 10.1.0) font display is worse than "better than nothing font" for small sizes #8084
Description
I'm using a small (128x32) OLED display, which is setup as 4 lines of text on a Raspberry Pi 5 running Ubuntu Server 24.04 LTS.
What did you do?
Upgraded my version of pillow (to any version from 10.1.0 or later)
What did you expect to happen?
My display to be readable.
What actually happened?
Some text is unreadable. In particular, the 6's look almost the same as 8's
