White map after rotate screen

[MaciejPachciarekSMT]

Environment

• Xcode version: 12.5.1
• iOS version: 14.4
• Devices affected: All
• Maps SDK Version: 10.2.0

Observed behavior and steps to reproduce

I open the map in portrait mode, loading all styles, layers, etc. On the end of loading (on styleDataLoaded event) I set the center of the camera to the map via mapView.camera.ease When it finish I also restrict the camera bounds as you suggested in this ticket (https://github.com/mapbox/mapbox-maps-ios/issues/820)

    func restrictCameraInsideBounds() {
        let southwest = mapView.mapboxMap.coordinate(for: CGPoint(x: 0, y: bounds.size.height))
        let northeast = mapView.mapboxMap.coordinate(for: CGPoint(x: bounds.size.width, y: 0))
        
        let restrictedBounds = CoordinateBounds(
            southwest: southwest,
            northeast: northeast
        )
        
        let cameraBoundsOptions = CameraBoundsOptions(bounds: restrictedBounds)
        try! mapView.mapboxMap.setCameraBounds(with: cameraBoundsOptions)
    }

However when I get mapLoaded event and without any touches rotate the screen map disappears. If I click on the screen map is still invisible, but when I made a drag gesture on the screen map appeared. What is funny when I perform some action i.e drag, zoom, etc. before I rotated screen map will be visible after changing orientation.

When I disable restrictCameraInsideBounds function map works perfect after rotate device

Expected behavior

Map should be still visible after rotate screen.

@MaciejPachciarekSMT thank you for reporting this behavior. I am able to reproduce on v10.2.0 - when restrictCameraInsideBounds() is outside of .mapLoaded the map works as expected when rotated, but when it's inside the closure, the reported behavior is visible.

@MaciejPachciarekSMT are you still experiencing this behavior? I am no longer able to reproduce.

[MaciejPachciarekSMT]

@ZiZasaurus are we talking about the 10.2.0 version?

Hello @MaciejPachciarekSMT, thank you for your detailed report, we are able to reproduce this issue in maps v10.6.0. We are planning to address it in Mapbox Maps SDK v10.8.0.

• Xcode version: 14.0
• iOS version: 16.0
• Devices affected: reproduced on iPhone SE 2020 and various Simulator devices
• Maps SDK version: 10.9.0

I can confirm this issue has been addressed for MapBox v10.8.1, however after bumping the version to latest stable (v10.9.0), I am again able to reproduce it.

@michalronin thank you for following up. Can you please provide a screen recording or sample project reproducing this behavior? I am currently unable to reproduce the behavior as outlined by the user above on v10.9.0. Please see my screen recording below:
