So I've been having weird issues with Spotify on my mac after updating to Mac OS Sierra 10.12.4 (and some graphics errors in Google Chrome coincidentally)
Most of the time, the issues have looked much like this:
The white squares appear around various buttons on the screen
Sometimes the text (song titles ect.) is displayed slanting across the screen, twice ive gotten large gray boxes at the top of the application and this happened to me last night:
I tried uninstalling & reinstalling Spotify today but alas the squares have returned. What could this be?
It has been determined that this is not a Spotify problem. It is suggested that you contact Apple for support.
