Any idea at all why, when I open Spotify sometimes, it would appear with this red translucent overlay around it??? I was viewing a photo in Photoshop below it and I find it strange the red halo is partly opaque, so you can see the programs underneath Spotify.
It did eventually go away on its own, but I was curious why this might happen, and/or if anyone else has seen this on an iMac.
Thanks for reaching out to the Community about this.
Most common issues can be fixed with a quick reinstall of the app. In some situations however, a clean (more thorough) reinstall of the app might be needed. This way you can start afresh with Spotify on your iMac.
Check out this help page in order to find the steps for clean reinstall on the affected device.
