Symbol layer flickering after zooming out

[moodstubos]

Mapbox 6.0 got an update for this (unfortunately after license change):

🐞 Bug fixes
Fixed an issue where symbols flickered when zooming out. (mapbox/mapbox-gl-native#16471, mapbox/mapbox-gl-native-ios/issues/273)

source 1: https://github.com/mapbox/mapbox-gl-native-ios/blob/master/platform/ios/CHANGELOG.md
source 2: mapbox/mapbox-gl-native#16473 (comment)

Found this issue in maplibre-gl-native android as well as ios.

Unfortunately I could not find any original commit in mapbox-gl-native repo for the mentioned fixes. I pretty sure its in the closed code therefore.

Perhaps someone has an idea where to begin for fixing this.
By the way: older versions of mapbox-gl-native-android (e.g. 8.6.7) does not have this issue (not yet tested for older ios versions).

Hi, I am the reporter of the issue mapbox/mapbox-gl-native#16471. Actually, I have a custom patch for some flickering issues, and I have uploaded it to ystsoi@52c2ce7. The patch is for Mapbox, and I have not tested it against MapLibre. However, I think that it should work on MapLibre too, please try it.

Hi, thank you for the patch! It works pretty well on Android.
However i'm still facing this issue on IOS... Did you find a solution for this ?

Update: After upgrading Mapbox IOS SDK to the last version using https://github.com/react-native-mapbox-gl/maps/blob/master/ios/install.md#mapbox-maps-sdk the problem disappear!

@gokugen, the provided link you've posted has nothing to do with MapLibre though - I'm posting this to make you aware of that.

THIS repo is MapLibre, when you follow the steps in (https://github.com/react-native-mapbox-gl/maps/blob/master/ios/install.md#mapbox-maps-sdk ) you will update the SDK version of the Mapbox iOS SDK, not of the MapLibre SDK.
