Mapbox-gl-native: Layers flicker during zoom

[cvance]

Fill Layers seem to flicker, artifact or get clipped when zooming in and out on a map with many layers. It does seem to stop after tiles have become cached.

@cvance - thanks for the issue report and reproduction! We believe https://github.com/mapbox/mapbox-gl-native/pull/14438 has fixed this issue, which went out in the latest alpha on both mobile platforms. Please let us know if you are able to reproduce with the alpha or with this PR. The next beta and final release are slated for the end of the month.

Initial impressions are looking very promising! Great news!

@cvance could you confirm whether the issue is fixed for you?

[cvance]

From everything I can see on the array of devices I've tested, yes. Fill layers seem much more stable now 😄

I do see this error in my logs from when I use our style based on mapbox's satellite style but it appears to work just fine.

Thanks @cvance! Glad to hear it. Hmm, that's weird. Are you using the onStyleImageMissing callback (https://github.com/mapbox/mapbox-gl-native/pull/14253)?

[LukasPaczos]

@cvance this means that there images that your style is looking for, but are not added to the map. You can listen to this event and react with the listener that @chloekraw linked (OnStyleImageMissingListener), but we've removed the log itself with https://github.com/mapbox/mapbox-gl-native/pull/14600 in the stable 7.4.0.

Closing this, @cvance please feel free to reopen if see fill layers flickering again. Thanks.
