Grey map on some Android devices

[David-Prelinger]

A customer reported grey tiles on the map. The customer has very good internet connection. On all other devices we tested with the same version, the map displayed normally.

Mapbox Flutter SDK Version: 2.5.1
The device: HUAWEI Mate 20 Pro
OS Version: EMUI 12.0.0
RAM: 6GB

The customer reported, that sometimes, the map actually gets displayed but then the whole app gets stuck shortly after.

I hope someone can help out to find the issue.

Wondering this this is the same issue one of my users is experiencing.... Here is the screenshot

Mapbox Flutter SDK Version: 2.7.0
The Device: HUAWEI
Android Model: CLT-L09
Flutter Version: 3.29.0

Keen to hear any updates on this one!

Here are our screenshots, sometimes it is a big rendering bug pattern but most of the time it just stays grey.

Thanks for reporting -- we are investigating on our side now.

Hey @pjleonard37. Have you guys managed to find out what's going on? We have had a few more users report the issue, even got a 1 star review so quite motivated to get to the bottom of this.

Let me know if there is any more information you need that might be helpful

Hi @kiwi-koder -

Thanks for checking in. We've been investigating, but have not succeeded in replicating the issue on our side making it difficult to debug. Do you have a code sample which reliably reproduces the issue (either on a physical devices or in an emulator)? If so, could you share it?

[kiwi-koder]

I haven't actually been able to reproduce the issue myself sorry! We managed to capture an error being produced by the person experiencing this issue though.

PlatformException(channel-error, Unable to establish connection on channel: "dev.flutter.pigeon.mapbox_maps_flutter._PointAnnotationMessenger.setTextIgnorePlacement.0"., null, null)

point_annotation_messenger.dart in _PointAnnotationMessenger.setTextIgnorePlacement at line 2417 within mapbox_maps_flutter

This particular error started appearing in our logs when we upgraded.

It looks to be happening on a range of devices across both ios and android. The two reports from users so far have only come from android, so maybe the error is being handled gracefully on ios or we just haven't had anyone using ios report the issue yet.

Hopefully that helps!

Hi @kiwi-koder -

Thanks for the additional information. We're still unable to replicate this locally, which makes it difficult to investigate (and confirm any potential fix).

One potential idea: which Android Platform View Mode are you using? Our default is Virtual Display, with which there are some known compatibility issues. Switching to Hybrid Composition may help here. Unfortunately, there are known issues with each mode (described here). You can control which mode is used with the androidHostingMode property.

We were able to capture this log from a physical device. Not sure if it helps you guys.
