Switching active cameras causes warning log The preprocessing index buffer wasn't present to be spammed.

What you did

Change the active camera by settings .is_active to false on the current camera, and .is_active to true on the camera view I'm switching to.

What went wrong

Log is being spammed with WARN bevy_pbr::render::gpu_preprocess: The preprocessing index buffer wasn't present

furthermore, the message changed from

Camera order ambiguities detected for active cameras with the following priorities: {(0, Some(Window(NormalizedWindowRef(0v1#4294967296))))}. To fix this, ensure there is exactly one Camera entity spawned with a given order for a given RenderTarget. Ambiguities should be resolved because either (1) multiple active cameras were spawned accidentally, which will result in rendering multiple instances of the scene or (2) for cases where multiple active cameras is intentional, ambiguities could result in unpredictable render results.
