I also encounter this on desktop in the web interface. It appears that this happens with federated posts. I.e. on Lemmygrad, the title is fine and not cropped, but for you on Lemmy, it’s cropped. Similarly, I, a Lemmygrad user, sometimes look at posts from Lemmy and they appear cropped, but if I click on the original link, they do not appear cropped on lemmy.ml.
