 | 1 | Bike Share, local data layers, Transit, Rail | 18 s freeze switching Bike Share on over New York (2,519 stations); 2.7 s on Data Centers; multi-second freezes with Transit while zooming | #1688, #1689 |
-| 2 | Shipwrecks | 3 to 5 s freeze when the markers are built over loaded terrain; a share link with the layer on held the loading screen for 22.9 s in one run | — |
-| 3 | Camera | Rendering stops until reload: at a whole-globe view looking straight down, pan a few times, then scroll one notch | — |

+| 5 | ALPR cameras | Depth samples inside the overlay paint, repeated on every re-enable: 240 samples and about 1 s across eight toggles. A first-sample freeze of up to 1.9 s was seen in the sweep but not on a second day | #1706 |
 | 6 | Wind | First zoom after load: up to 14 long tasks (longest 414 ms). Re-measured as one-off shader links, not a standing cost: see below | none proposed |
