If you are a Spotify user or willing to download it and have Lumia Denim, please could you test Spotify this week on your Lumia 930? I want to find out if you get the same flickering problem that I did on two Lumia 930 phones. Spotify isn't the cause of this issue, but it first became noticeable as I was using Spotify.

If you experience flickering whilst using Spotify or any other Windows app, please notify Microsoft as there appears to be a problem with the Lumia Denim update.

If you don't experience anything that shouldn't happen at all, please also let us know.

I use Spotify on my 930 and I have Denim, I get no flickering issues.

Thanks, looks like the two 930 phones I had to return to Amazon probably did have a hardware issue then.
If it was only a software issue it should have been replicated on your phone.

I used to experience some flickering, but it was completely random. Mostly never twice in the same app.
