Error is thrown when using the progress bar API along with Texture compression

Progress Window


When we use the function EditorUtility.CompressTexture inside a code that displays a progress bar, the progress bar doesn't show up and there is an error message in the Console Window.

How to reproduce:
1. Open the attached project "case_1308740-Project"
2. Click on the "Tests/Compress Texture Test" menu
3. Observe the Console Window

Expected result: Progress bar is shown and no errors are thrown
Actual result: Progress bar is not shown and "Trying to access current progress scope, but the scope stack is empty" error is thrown

Reproducible with: 2020.2.0a8, 2020.3.0f1, 2021.1.0b11, 2021.2.0a8
Not reproducible with: 2018.4.32f1, 2019.4.22f1, 2020.2.0a7

Note: In some versions, the progress bar is shown briefly

    Fixed in Unity 2021.1.1f1

  2. Resolution Note (fix version 2020.3):

    Fixed in Unity 2020.3.3f1

    The problem with Texture2D.Compress() is that it only works for DXT textures and is of lower quality.

    Freak is it the EditorUtility.Compress() that is triggering this bug? I am just wondering if my experience in Microsplat is related to this bug.

    Temporary workaround: Replacing with Texture2D.Compress() worked so far.

    Can confirm for 2020.2.2f1, found no solution to this yet :(
