Why does the text in my Timeline look blurry? (macOS)
You may on occasion notice blurry text when using Twitterrific on macOS Sierra or macOS High Sierra. This occurs sporadically, and we are working to rectify the issue in a minor update as soon as possible. The easiest way to clear the problem is to click on a background app or another Twitterrific window and then click back to the window experiencing the issue.
If the issue persists, quit Twitterrific and then re-launch the app.
