    @wojimus this bug has been known since 2020, not 2015. AsyncGPUReadback wasn't a class in Unity until 2018 and RequestIntoNativeArray wasn't a method until 2019. It's impossible for a feature to have bugs before it even existed.

    In any case, we can see on the issue tracker here the "Fix is in Review" meaning a fix has already been made internally, and is almost ready to release publicly. It's just going through a quality testing process. more info here: https://forum.unity.com/threads/asyncgpureadback-requestintonativearray-causes-invalidoperationexception-on-nativearray.1011955/#post-7150846

    I think this should be moved to graphics.
