# Objective The `U32Visitor` struct has been unused since its introduction in #6140. It's made itself known now by causing a recent [CI failure](https://github.com/bevyengine/bevy/actions/runs/8243333274/job/22543736624). ## Solution Remove the unused `U32Visitor` struct. Also removed `PrepassLightsViewFlush` as it was causing a [similar CI failure](https://github.com/bevyengine/bevy/actions/runs/8243838066/job/22545103746?pr=12433#step:6:269) on this PR. |
