Annotations disappear from some tiles until panned out of view or zoomed

[JosephShering]

I'm using Swift with the Mapbox iOS SDK. Is there a way around this issue?

Having the same problem when I use 'showAnnotations(..).

[BenjaminDigeon]

Having the same problem too, with objective-c.

Wonder if this could be fixed by #2951.

[picciano]

Not to join the "me too" bandwagon, but we've started seeing this in the past few days. Possible regression of #1675 ?

@jfirebaugh, did you run into this problem while refactoring annotations at the core level?

[jfirebaugh]

I'm not able to reproduce this in our annotation tests or in the test app. Can someone share example code?

[picciano]

This test project demonstrates the issue.
https://github.com/tallygo/MissingMapMarkers

The map should display a map with a polyline and two annotations. Tapping the "redraw" button will instantiate a new map. The results are inconsistent, you will often see part of the line missing, one or both annotations missing.

This problem seems to come and go with different builds.

This started worked reliably in https://github.com/mapbox/mapbox-gl-native/tree/85ab48636c0f0cb5b1ec5c5b6b64a41dbd188e06

But has since regressed again. It's not working well in ios-v3.0.0-pre.9 at all. In fact, of the releases, I have to go back to ios-v3.0.0-pre.2 to find good working version.

I can confirm this issue. I have exactly the same for the pre.9 build.

I’m unable to reproduce the issue in the MissingMapMarkers sample application using Mapbox iOS SDK 3.0.1 on an iPhone 6 running iOS 9.2.

[picciano]

I'll check that out, thanks for the update

[picciano]

I agree, 3.0.1 is working great. No missing point or line annotations.
Do we know what caused this?

[jfirebaugh]

This probably settled down with 7669e02.
