WebCamTexture does not unload textures

I am having an issue with the WeCamTexture class. Once I call the Play() function and begin collecting textures, the textures remain in memory for as long as the program is running which causes them to pile up in memory and crash, not only Unity, but sometimes my entire computer, forcing a restart. Calling Pause() or Stop() stops the collection of textures but does not remove them from memory. I am using version 2018.3.1f1
