Texture size increased on first build when 'Compress Textures/Assets on Import' is enabled

Asset - Database


How to reproduce:
1. Download the attached project ''
2. Make sure to disable Preferences > Asset Pipeline > Compress Textures on Import (on Unity 2020.3 or older: Preferences -> General -> Compress Assets on Import)
3. Build the project
4. Open Editor.log and look for the line that shows the size of 'Assets/Art/Dolphin/dolphin_texture.JPG' (use ctrl + f)

Expected result: Logs print '512.1 kb 0.5% Assets/Art/Dolphin/dolphin_texture.JPG' (the % number can be different)
Actual result: Logs print '3.0 mb 3.1% Assets/Art/Dolphin/dolphin_texture.JPG' (the % number can be different)

Reproducible with: 2019.4.33f1, 2019.4.35f1, 2020.3.20f1, 2020.3.28f1, 2021.2.0b15, 2021.2.11f1, 2022.1.0a9, 2022.1.0b8, 2022.2.0a5

Notes: The issue only reproduces on the first build, any builds after that get the expected result. Need to delete Library folder to reproduce the issue again on the same project

    I'm currently fighting a similar issue. It's made my project impossible to open now.
