Summary:
For a while now I've been seeing an issue in the "Recently Added" section of iTunes. The album artwork and headings (like "This Month") flash whenever the view is updated. By "flash", I mean that the content disappears completely and then reappears immediately after. A single flash can happen when a song is updated (for example by clicking the "love" button") or multiple flashes can happen if an album or playlist is downloaded.

Steps to Reproduce:
- This is probably easiest if iTunes Match and/or Apple Music is enabled, since that allows you to remove something from your computer and download it again.
- Make sure you have at least one album in your library. If the album is already downloaded to that computer, remove the downloads.
- Select the "Recently Added" section
- Click on the small album cover to reveal the large album cover and track listing.
- Make sure one of the large, bold headings is in view, like "Today", "This Week", etc.
- Click the download button for the album

Expected Results:
Nothing should flash (disappear briefly) when the view is updated.

Observed Results:
Every time the view is updated, the bold headings and large album covers flash briefly.

Version:
iTunes 12.6.2.20 and macOS 10.12.6 (16G29). I've been noticing this problem for months so it definitely is not specific to either version.

Notes:
I'm attaching a video of the problem happening. The album was downloading while I captured this video.

Configuration:
I'm confident it's a bug in recent versions of iTunes and not specific to any particular macOS software or hardware configuration. I've had it happen on a 2014 iMac, 2017 iMac, 2016 MacBook Pro with TouchBar, and 2014 MacBook Pro.
