This issue could be reproduced by several users:

1. The display suddenly splits [1] up and the text breaks
2. The Monocle suddently restarts
3. The buttons suddenly stop working and suddenly start working again after a long press, but then it takes a picture when not really willing to

[1] I suppose that means that an offset in the text makes it go over one edge of the display and appear back from the other

This sounds like 2. and 3. are a consequence of 1.

The next font engine could be a fix for it. If this issue still persists even though the entire font engine has changed (from FPGA to firmware to python wrapper), then the problem is likely coming from elsewhere. Maybe a fragment of code kept across versions, or a fragment of code sent to the Monocle.

It is also possible that a forbidden character appears such as a newline or UTF-8 character.
