I’m uploading a image with “https://upload.twitter.com/1.1/media/upload.json” and linking to a tweet (using Unity 3D). At end of the process, i notice that the PNG transparency was not respected, but doing this with “https://api.twitter.com/1.1/statuses/update_with_media.json” in the API Console Tool, all seems to be fine.
Also, report that when sending a 144x144 PNG it appears with strange white strokes on the transparent part that became black.
I would like to know what i might be doing wrong, or if is a twitter API issue.
