In the screen shot above the notification partially appear how fix the font
Is this issue related to:
Would FC add “yMin value” “yMax value” item for Android in ?
I learned a trick from John Hudson, that overcomes the issue by adding a glyph that is completely useless, except for the fact it contains a rectangle with top set to WinAscent and bottom to WinDescent. That way Y Maximum and Y Minimum reflect WinAscent and WinDescent.
If your font already contains glyph outlines that exceed those values, then this is of course of no use.
Let us know if this solves your problem.
