Adobe - Letter preview wrong when zooming in

Hi, i created a font with negativ digits. If i zoom in over 250% in InDesign/Acrobat , the font will be displayed incorrectly. I only see black circles there. Is there a solution for this in the settings of Glyphs? Or how can i solve this problem?

Thank you

  1. Make sure your path directions are all correct. In Font View (Cmd-Opt-1), select all glyphs (Cmd-A) and choose Paths > Correct Path Directions (for all Masters) (Cmd-Shift-R, add Opt for all masters).
  2. Exclude font cache problems by using the Adobe Fonts folder.

THX :pray: Works perfect without using Adobe Fonts folder
