How to reproduce:
1. Open project "TicketProject.zip"
2. Open scene "TestScene"
3. Set OpenGLES2 or/and OpenGLES3, but remove Vulkan in Projects Settings -> Player -> Graphics APIs (after disabling auto Graphics API)

Expected result: Sprite Renderer in the middle of the scene constantly changing its color
Actual result: Sprite Renderer stops changing its color after 0.5 seconds from the start
