Graphics.RenderMesh stops rendering when game is paused

Steps to reproduce 

1. Create a project using the builtin renderer
2. Create a script with the code from https://docs.unity3d.com/ScriptReference/Graphics.RenderMesh.html to draw meshes
3. Play the game. The meshes will be drawn correctly.
4. Pause the game
5. Notice that the objects are not drawn anymore. If the game is unpaused it will be drawn again correctly.
