SpriteAtlas.GetSprite will always cause increase in memory as it clones the Sprite Object, this is expected. Calling the API frequently will hence cause a more noticeable memory increase API Docs: https://docs.unity3d.com/ScriptReference/U2D.SpriteAtlas.GetSprite.html

Reproduction steps:

Open the user’s attached project “MemLeak_Project“
Open “Assets/Scenes/SampleScene.unity“ Scene
Enter the Play mode
Open Profiler (Window > Analysis > Profiler)
Observe slowly increasing memory usage

Expected result: Memory usage is not increasing
Actual result: Memory usage slowly increasing

Reproducible with: 2021.2.0b13, 2021.2.19f1, 2021.3.16f1, 2022.1.24f1, 2022.2.2f1, 2023.1.0a23
