App icons in iPad dock are fuzzy due to smaller rendering size than home screen icons

Status:Open Resolved:
Product:iOS + SDK Product Version:12.1.1 (16C50)
Classification:UI/Usability Reproducible:Always
 
Summary:
Icons for apps moved to the "dock" of the iPad home screen are rendered with a size of 73x73pt instead of the expected 76pt.
As the icon PNG file we are asked to provide is for the 76pt size, icons in the dock are scaled down and the artwork may appear fuzzy (fine lines for example are crisp on the home screen and fuzzy in the dock).

Steps to Reproduce:
1. Install 2 apps with the same icon artwork
2. Move one of the apps to the dock
3. Compare the two icons (I expect the difference to be more visible on a retina screen)

Expected Results:
The icons look the same

Actual Results:
The icon in the dock appear fuzzy

Version:
12.1.1 (16C50)

Notes:
Attached is a screenshot of our icon app on an iPad mini screen. If opened in a image processing software we can easily see the difference between the two icons.

Comments

I only just realized iPads now allow for multiple icons in the dock, which results in the icons being dynamically resized. So this probably isn't a bug but working as intended.

Closed the bug report (which was previously marked as duplicate of 39255027).
