Hey CatBus, IIRC you posted a while back saying that you had developed your own software for rendering subtitles. I’ve been using easySUP to make my own .sup files from .ass files for years now for authoring subtitled anime Blu-rays, but the subtitles always flash when two or more subtitles have overlapping timings (really annoying when two characters are speaking at the same time, or when there’s onscreen song lyrics). Recently tried PunkGraphicStream but get the same problem (and now I can’t even run the software anymore since it started giving me a java.lang. unsatisfiedlinkerror).
Looked around doom9 for a solution but couldn’t find one, so thought I’d ask if you have this problem with your software.
