Apparently the directives that the OFFLINE converter is placing are not compatible with LVGL 9.3.0 #138
Description
When trying to specify another font in the style that is not linked in the LV_FONT_DEFAULT definition, the screen gets stuck where the letter would be displayed.
I copied the instructions from the footer of the lv_monterrat_18 font file to the lv_freesans_18 font file. Now it works.
