You clearly haven’t tried 3.5e, IMHO best edition. Class for every occasion. 362 to be exact, however I might be missing some (ex. savage species monster class progression). And you can obviously mix and match classes as long as you meet the requirements.
I see this whenever I view a really long image in a Lemmy app. If you view it directly in browser then it does become legible, but it’s definitely a bug.
