Wide vector rendering issue on MapTiler Streets #1453

Open TimSylvester opened 3 years ago

TimSylvester commented 3 years ago

The N/S section of SE 172nd between Sunnyside and Hwy 212 (ZIP 97015) renders incorrectly around level 9-10. There's also some kind of artifact on Rock Creek Blvd. extending to the West at 11-12.

The source of this issue is commit 20a01e75b, 7 Jan 2021 which improves the rendering of turns.

Backing off these limits, from [0,1] to [-4,5] and back to [-1,2], makes this problem less severe while retaining some of the benefits. See ce9d3fe0.

The long-term solution is to switch to the new "performance" wide vectors and discard this implementation.
