Line rendering problem

[jingsam]

Recently I upgraded mapbox-gl-js from 0.11.0 to 0.20.0, some wired artifacts appear with line feature rendering.
ENV: Windows 10, Chrome 51, vector tile v2(created by tilelive-bridge)

I have created a jsFiddle. Please help me, thanks.

What's the buffer size on those tiles?

[lucaswoj]

I wonder if this could be a true positive of the "Geometry exceeds allowable extent" error message.

ref #2568

[jingsam]

@mourner I use tilelive-bridge to generate vector tiles. I use the default configuration, which the extent should be 4096 and buffer is 128, I guess.

Here is one of my tile: http://218.244.250.70:8090/api/v1/tilesets/foxgis/admin2/8/210/99.vector.pbf

I remember seeing a very similar issue earlier but can't recall the number...

[jingsam]

checkout this:
#1679
#1680

I tried to render my style using mapbox-gl-native, same problem happens. Maybe it is the new earcut engine causing the problem?

[jingsam]

I get the warning:

Geometry exceeds allowed extent

So confirmed it is the problem of buffer size

[andrewharvey]

possibly the same issue as #2676 (though I only notice it for large a canvas of 4096px)

@jingsam are you still seeing the "Geometry exceeds allowed extent" warning message using v0.21.0?

[jingsam]

@lucaswoj Yes, v0.21.0 has the warning: Geometry exceeds allowed extent, reduce your vector tile buffer size http://jsfiddle.net/jingsam/9g7otrp5/1/

[lucaswoj]

@jingsam can you try reducing the vector tile buffer size?

This problem should be fixed by reducing your buffer size.
