I'm seeing many reports of unhappy users with failing watchfaces. Please fix this as soon as possible Garmin.

    You are not reading my comment, or have confused yourself by adding lineHeight to the mix.Please re-read the quote from the post above.

    What I said is consistent with what the bmfont docs say.. base is the height from the base line to the top of the tallest glyph. The char height is the height of the full character glyph- the base height plus any descender. But note that I specifically say we consider the digit height to be the height of the ‘0’ glyph, which would not normally have a descender.

    Your font has base height=13, and digit height is either 13 or 17 depending on whether or not ‘0’ is in the character set. If you leave out ‘0’ from the chars, your font will not crash the app. If you put it in, it will crash.

    If you have examples of ttf/otf font files that these conditions do not hold, please provide them.

    I'm on a Mac en therefor are using the Hiero tool to convert my fonts. The Roboto font (free download on Google Fonts) causes this issue for example.

    When I manually set base height equal to the size of the 0 char in the .fnt file it works. So I've been through a lot of work to manually adapt all font files for all devices on all my products. It's just super odd this is suddenly handled differently on the FR645M device, while it even still works on the Simulator.
