2022.1 has reached end of life so the issue will be fixed in a newer version.

2021.2 has already reached end-of-life.

Closing since this version is not supported anymore, and there is another port to track 2021.3 which is the supported version

2020.3 has reached end-of-life.

2019.4 LTS has reached end-of-life. This port is cancelled.

How to reproduce:
1. Open the attached “CookieBug.zip” project
2. In the project window select the “Cookie.png” image in the Assets folder

Expected result: In the Inspector Mapping can be changed
Actual result: In the Inspector Mapping can not be changed

Reproducible with: 2019.31f1, 2020.3.20f1, 2021.1.25f1, 2021.2.0b15, 2022.1.0a12

Notes:

Mapping setting is available when “Light Type” is “Point”
The expected result can be achieved by changing the “Non-Power of 2” option to anything else that isn’t “None”
When clicking apply the greyed out mapping option gets applied
Does not matter if the texture is POT or not. ( Tried with the base texture of 256x256 and 384x512 sizes)
