# Objective
The `prepare_view_upscaling_pipelines` system has dozens of ambiguities,
which makes it harder to spot and prevent new ambiguities.
Closes https://github.com/bevyengine/bevy/issues/14770.
## Solution
Just exclude the system from ambiguity detection. See the linked issue
for more context on why this resolution was chosen.
## Testing
Running the `ambiguity_detection` example now reports dozens fewer
`Render` app ambiguities.
