The issue
When upgrading a Unity project from 2021 to 2022, after AVPro Video finishes playing a video, the VRAM continues to increase. Even after the video playback is completed and Stop and CloseMedia are called, switching to using an external RenderTexture and explicitly releasing it afterwards does not resolve the issue. Each time a video is played, the VRAM grows incrementally.
Media information
Any video can cause this issue.
