I want to display something similar to the history in the Activity app, but for the sake of this question it's a simple pie diagram instead of 3 rings. I created a custom UIView and use draw(in ctx:) to draw the pie.

The trouble is that when I scroll and cells get reused, the pie persists in those cells for a brief moment before being redrawn.

Here's how to reproduce this:

1. Create a new single view project
2. Copy paste the code below in ViewController.swift and Main.storyboard
3. Build & Run
4. Scroll down: you'll see a bunch of colored dots. Scroll some more and you should see the blinking dots.

Things you might ask:

• It's a simplified "calendar" of 10 months with 30 days (cells), and only the 2nd month has dots to showcase the issue.
• I add pieLayer as a sublayer of the UIView layer instead of using the layer directly because, in my project, I have more than just one custom layer
