# Objective - Fixes #14265 ## Solution - Go through Pixel Eagle examples (and examples all in all) - If default size is used it is usually left there - If size of font is touched try dividing with 1.2 and round it to nearest whole number ## Testing - Run example before and after - Make sure examples text are readable or like before cosmic-text change --- ## Showcase Before:  After:
