Panning in offline mode with terrain is stuck sometimes #1654

mfazekas · 2022-10-18T11:45:28Z

Environment

Xcode version: 14.0.1
iOS version: 16.0
Devices affected: Device iPhone 13 Mini, Simulator - iPhone 14 Pro
Maps SDK Version: 10.9.0.rc1

Observed behavior and steps to reproduce

offline-map-stuck-lr3.mov

Happens around 20sec of the video. The panning stuck.

Logs around there at the end of report, I do see logs for pan statement, but the pan actions are not doing anything for a while.

To reproduce start the app, press download button, wait for the download to complete, turn off wifi. And start panning in one direction.

Code used:

import UIKit
import MapboxMaps

let accessTokenSch = "pk....";

  func move(latitude: Double, longitude: Double) -> LocationCoordinate2D {
    return LocationCoordinate2D(latitude: self.latitude + latitude, longitude: self.longitude + longitude)

Seeing the same thing and it's really problematic for us. Any insights on this from Mapbox would be very appreciated as well.

astojilj · 2022-10-24T06:18:15Z

I don't think this is related to the connection issue, but could you please set RasterDem source max zoom to 14?
For tile size demSource.tileSize = 514, max zoom is 14, there are no tiles at zoom level 15.

Is the same reproducible on Android or with mapbox-gl-js?

astojilj · 2022-10-31T07:42:21Z

@mfazekas

Could you please set maxZoom to 14, like in the Maps SDK example?

mapbox-maps-ios/Apps/Examples/Examples/All Examples/TerrainExample.swift

Line 39 in 6b0e373

demSource.maxzoom = 14.0

Need your help in identifying the issue:

the lost connection. Does this happen when connection is on (when not running offline mode)?
panning slows down as camera is closer to ground and pitch changes. This issue is addressed in Prevent pitching when zooming into terrain mapbox-gl-js#12280 (comment). This looks like the same issue - were you able to zoom out once the camera panning gets stuck?

mfazekas · 2022-10-31T09:21:56Z

@astojilj sorry for late answer,

I did add demSource.maxzoom = 14.0 but still saw the issue.

the lost connection. Does this happen when connection is on (when not running offline mode)?

No I don't see lost connection, just when testing with wifi off.

panning slows down as camera is closer to ground and pitch changes.

Yes I think this is the issue we're facing here. Yes when stuck I can zoom out then panning works again.
