[iOS] Player crashes during animation 'UnityGfxDeviceWorker' UnityFramework`void TransformVerticesInnerLoop

Package: 2D Animation


Reproduction steps:
1. Open the project in ""
2. Open "SampleScene"
3. Build and Deploy the project to an iOS device
4. Wait for around 10 seconds

Unexpected behaviour: at one point during the animation (the character will be throwing seeds), the application crashes

Reproducible with: 2019.4.18f1, 2020.1.17f1, 2020.2.2f1, 2020.1.0b2, 2020.2.0a2
Could not test with 2018.4.31f1 because the character becomes invisible (and possibly something else gets removed as the application does not crash)

Note: sometimes the issue does not reproduce (only encountered on OpenGL ES 2, 3), the repro rate was around 2/3 though

  1. Resolution Note (fix version 7.0.0-pre.2):

    The crash has been traced back to disabling SpriteSkin components. The issue was that we released the SpriteSkin's vertex buffer on disable. In the updated solution, we have moved the vertex buffers to a shared manager to prevent the memory being disposed when being used.

    Fixed in 2D animation 5.0.5
    Fixed in 2D animation 6.0.3
    Fixed in 2D animation 7.0.0-pre.2

  2. Resolution Note (fix version 7.0.0-pre.2):

    Fixed in 2021.2.0b3.3078

  3. Resolution Note (fix version 3.2.8):

    This is fixed on 2D Animation 3.2.9
