When the CurveLinearColor asset assigned to a CurveLinearColorAtlas is edited (e.g. change the colors of the gradient), the preview window of CurveLinearColorAtlas editor does not automatically update and has to be manually dirtied to see the new changes represented. This causes issues with the licensee's artist workflow.
1. Create a CurveLinearColor asset.
2. Create a UCurveLinearColorAtlas asset.
3. Link the Curve asset up into the Atlas asset.
4. Modify the original Curve asset.
5. Observe that the atlas texture itself (in the texture preview window) does not update, until the atlas asset itself is dirtied in some way.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-230273 in the post.
