Script recompiles in Play Mode when Script Changes While Playing option is set to Recompile After Finished Playing and Auto refresh is set to enabled.

Nov 29, 2022

Reproduction steps:

# Open the user’s attached project “ReproProject”
# Open the “_Assets/Test.unity_” scene
# Navigate to “_Preferences/General/Script Changes While Playin_g” and set it to “Recompile After Finished Playing”
# Navigate to “_Preferences/Asset Pipeline/Auto Refresh_” and set it to _Enabled_
# Enter Play Mode
# Open the “_Assets/Test.cs_” script, uncomment line 11
# Save the script and return back to the Editor

Expected result: Script does not recompile in Play Mode
Actual result: The script recompiles while still in Play Mode

Reproducible with: 2021.1.0a8, 2021.1.28f1, 2021.3.15f1, 2022.2.0f1, 2023.1.0a20
Not Reproducible with: 2020.3.42f1, 2021.1.0a7
Reproducible on: Intel macOS 13.0.1

Note: Changing the Auto Refresh selection to “Enabled Outside Play Mode” seems to stop the recompilation in Play Mode.

Resolution Note (fix version 2023.2.0a11):

Asset Pipeline: Prevent script re-compilation when 'Recompile after playmode' and 'Auto-refresh' are set.

Please address the issue ASAP and backport it to 2021. This is critical for fast iterations and debugging.
It is hard to believe that the issue has not been resolved yet after it was found in so many versions.

Thank you Unity Devs for the hard work by the way. We know that this is just a prioritization issue.

This issue is preventing us from migrating from the 2020 LTS to the 2021 LTS. This breaks a specific workflow for us. Hoping that this will be fixed in the 2021 LTS soon.

Would greatly benefit from having this fix in 2021.3 LTS, it's affecting the ability to iterate quickly with UI Toolkit and updating uss and uxml files while in play mode.
