Thanks @bonnell, yes I’ve been using twitterkit since around v1.9.0. It’s happening to every TWTRTweetView in my app.

In my table view of TWTRTweetTableViewCell sometimes they also sometimes exhibit the same low quality images, but sometimes they appear good quality. But I just saw a TWTRTweetTableViewCell start out low quality, then I scrolled past it, then scrolled back to it, and it suddenly popped into high quality.
Other examples of low quality TWTRTweetView images for reference:
