Its kinda of a TFF prob whenever i want to change my avatar, the new one is the same pic but the size as the new.Sorry for spamming if its in a diff forum
Your avatar at the moment looks fine, not blurry or anything. But I know what you mean, it stretches to the size of the old one. Try uploading the new av, then once it finishes, refresh the page.
