Issue ID
1397965
Regression
Yes
Texture size increased on first build when 'Compress Textures/Assets on Import' is enabled
How to reproduce:
1. Download the attached project '1397965.zip'
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
Not reproducible with: 2019.4.32f1, 2020.3.19f1, 2021.2.0b14, 2022.1.0a8
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

Every build is a 'first build' because we use docker containers to build our game. So this prevents us from upgrading to 2021.
My collegue's comment from the related issue:
> This essentially makes these unity versions not viable for production in our case.
Multiple LTS versions are affected which are supposed to be stable and production ready.
There seems to be no workaround which means that we are stuck with 2019 LTS for the time being. I don't understand why this is not being fast tracked. It has been unresolved for multiple weeks. It essentially makes the new unity versions unusable for every game studio that is developing mobile games where download size matters.
Please fix this ASAP.Related issue: https://issuetracker.unity3d.com/issues/textures-not-compressed-when-building-bundles
Does disabling 'COMPRESS TEXTURES/ASSETS ON IMPORT' actually workaround the bug in Unity 2021? Is there an editor method to disable this option?

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