Problems with the raster_hinted preset in textmeshpro

hi. i tried to generate a font in textmeshpro, and while all atlas generation presets work absolutely fine, i have a problem with exactly one preset: raster_hinted, which is used for pixel fonts. when i try to generate it, some characters come out as random jumbled pixels (see picture below)


it works like that even with the default liberation sans font btw. is there any way to fix that? or maybe unity just messed something up in their code. either way this isn’t how it should be
