Issue with layers getting "cropped" on pan/tilt

[tbassett44]

mapbox-gl-js version:
0.39.1

Steps to Trigger Behavior

The issue seems to be prevalent when the bearing or tilt are non-zero, other than that, this issues seems to be pretty hit or miss. Even though there are many layers configured in the same way, it only sometimes happens.

Expected Behavior

Markers should show in their entirety regardless of pan/tilt, especially with "icon-allow-overlap":true

Actual Behavior

Markers sometimes get cut off or dont show at all. See images below.

In the images below, a marker is animated across the map (non zero pan/tilt values). Interestingly, it started off as completely hidden, then as the marker moved, it slowly came into view with a clear line cutting off some of the marker.

Any help with this would be greatly appreciated, thanks!

@tbassett44 this is likely related to #2706.
I had a similar issue. You could try to increase the tile buffer or set "icon-allow-overlap":false .

[tbassett44]

@pathmapper How/where do you change the tile buffer? Not seeing much documentation on that (https://www.mapbox.com/mapbox-gl-js/style-spec/#sources-geojson-buffer). I tried a buffer of 512 on the source in question and it had no effect, it still clips. Setting "icon-allow-overlap":false seems to fix but for the application, it needs to be set to true. Will work as a work around for now

Thanks for the quick response!

[pathmapper]

@tbassett44 are you using a custom or a Mapbox tileset? When you are creating a custom tileset you could use Mapbox Studio Classic. There it is possible to set the buffer size in the data layer options. Or you could use tippecanoe with -b option. With the current Mapbox Studio I think it is not possible at the moment.

@tbassett44 can you provide a jsfiddle or jsbin that reproduces this behavior?

[tbassett44]

@mollymerp It is not being reproduced here, but I made a lot of headway on the jsfiddle. I have a feeling this might be due to the complexities of the overall map being built. Will put in the time when I have it to try to reproduce entirely.

Wow, thanks @pathmapper!!! Seeing as you were able to reproduce, does this fit with what you were saying above? We get our tiles from: https://openmaptiles.com/ and we have a custom tile serving mechanism.

Can't reproduce with v0.42.0: https://jsfiddle.net/gxc5ca9d/15/

Seems that #5150 fixed it.

Thanks @pathmapper ! Glad to hear it.
