Steps to reproduce:

  1. Clear page cache if any
  2. Open https://ssd.skhynix.com/jp/platinum_p41/
  3. Wait until the animation of the first image ends.
  4. Scroll the page

Actual Results:
The image animates according to the scroll position of the page.
But sometimes the image flickers(for a moment, it goes black).
Screencast: https://youtu.be/0h7Q7h4mW_I

Expected Results:
The image animates without flickering. Chrome works as expected.

Note:
This issue is also seen in Firefox 78.

Attached file about:support

The page is toggling display none on a series of images to perform the animation and it's expecting sync decoding.

Severity: -- → S3
Priority: -- → P3

Setting image.decode-immediately.enabled to true eliminates (reduces) flickering except image of the last asteroid.
In addition to the above, setting image.mem.decode_bytes_at_a_time to 256000 will also eliminate flickering of image of the last asteroid.
