1293947 - GeoJSONs on Map SVGs break and restitch map when zoomed in zoomed out.

Status: NEW

(Core :: Layout, defect, P3)

Description

[Sudheesh Singanamalla (:ShellHacker)]

Attachment: Map Stitching Breaks.png

Steps to Reproduce:

1. Go to https://gist.github.com/jasondavies/1284044 and scroll down to the leaflet geojson layer visualization
2. Zoom in and out of the geojson and you'll notice that the layer of UK is maintained as we zoom in and then re-adjusts itself causing it the feel of breaking and restitching.

This is not the same behavior experienced on Chrome and IE/Edge. Screenshots attached with the bug report

This works correctly for me, in Nightly 51.0a1 (2016-08-15) as well as in Firefox 48 release.  I'm on 64-bit Ubuntu Linux 16.04.  Maybe this bug is Windows-specific? (Or perhaps Hi-DPI specific?)

It works fine on mac and ubuntu, I think this is windows specific and not necessarily hi-dpi specific, it also breaks on non hi-dpi screens.
