Reproduction steps:
1. Open the attached "IN-126517-REPRO-V2.zip" project
2. Open the “Assets/Repro/TheScene.unity”
3. Open Frame Debugger (Window > Analysis > Frame Debugger)
4. Enable Frame Debugger
5. Switch to Game view
6. Observe Frame Debugger
Actual result: Amount of draw calls constantly shifts, preview "Output" flickers
Expected result: Amount of draw calls remains the same
Reproducible with: 10.0.2 (2023.2.0a12), 10.2.2 (6000.0.65f1), 13.0.2 (6000.3.4f1), 14.0.2 (6000.4.0b3, 6000.5.0a4)
Could not test with: 10.0.2 (2023.2.0a3) (Sprite skin component shows as missing script)
Reproduced on: Windows 11
Not reproducible on: No other environments tested
Notes:
- The issue does not reproduce if the Scene view is active and positioned near the Game view (their views align)
- The issue is inconsistently reproducible on 2023.2.0a3, if you start switching 2d animation package versions 10.0.2 and 10.0.3, until Sprite Skin component appears
- In the original customer project, the issue reproduces much less frequently and primarily when the object with Sprite Skin is near the edge of the Game view
- Issue only reproduces if the Sprite Skin component has a Root Bone assigned and a bone present in the Bones list (Not tested with multiple bones in the list)
