Mapbox-gl-js: incorrect bounds on composited sources cause tiles not to load

[karlguillotte]

mapbox-gl-js version: 0.35.0 and above

Steps to Trigger Behavior

1. Upgrade from 0.34.0 to 0.35.0
2. Zoom in and out to see blank tiles: http://avalanche-canada-dev.elasticbeanstalk.com/map

Expected Behavior

I would expect all tiles to be displayed at all zoom levels.

Actual Behavior

Some tiles are blank as user zoom in and out. Here is an example of the issue: http://avalanche-canada-dev.elasticbeanstalk.com/map

I am still investigating the issue, wondering if others have experienced that issue.

I am using the smart style setter and I have some markers on my map, But it does not matter that much because even the Mapbox map previewer shows blank tiles as well: https://api.mapbox.com/styles/v1/avalanchecanada/citxsc95s00a22inxvbydbc89.html?fresh=true&title=true&access_token=pk.eyJ1IjoiYXZhbGFuY2hlY2FuYWRhIiwiYSI6Im52VjFlWW8ifQ.-jbec6Q_pA7uRgvVDkXxsA#4.11/54.971/-124.276

Thanks for your hard work on Mapbox GL!

Hi @karlguillotte – thanks for this report and I'm sorry this bug is affecting you. I'm pretty sure this is related to #4556 and the automatic compositing our maps API does (in addition to our API incorrectly stating the bounds of the composited source are the bounds of your avalanche source 😞 )

One thing you could try while we work on fixing this is turning off compositing in Mapbox Studio (or just staying on 0.34.0 until we ship a fix)

Thanks @mollymerp ! I will stick to 0.34.0 for now.

^ this in combination with #4556 I think should be release blocker/higher importance as it breaks a lot of maps.

People are running into this issue https://gis.stackexchange.com/questions/236428/not-all-tiles-loading-in-view-web-with-mapbox/236967#236967

Thankfully https://www.mapbox.com/api-documentation/#embed-a-style is still pinned at 0.34.0.

@andrewharvey yep I rolled back the api-styles share page to 0.34.0 on Friday because of this. This is a problem with another Mapbox service, not gl-js, so its not a release blocker for this repo. I should have a fix shipped on our Maps API soon – just keeping this issue open for visibility.

[andrewharvey]

This appears to be fixed in the API. :tada:

[mollymerp]

Yes! I pushed a fix to the maps API and bumped up the styles share page to v0.36.0. You should be good to go. Thanks for your patience!

Amazing! Thanks @mollymerp
