Problems with Vector Tiles in Chrome

JeffreySchmidt3000 — Thu, 16 Jun 2016 16:28:22 GMT

I have noticed that Vector Tiles do not behave as expected in Google Chrome. I have the most up to date version of Chrome. Tiles will appear blocky or expand past their boundaries causing polygon colors to overlap portions of a map. This occurs in the Sample Code sections of both 3.16 and 4.0 APIs. I do not see this same issue in Edge, FireFox and IE.

Is this a known issue with Chrome? It appears to behave in Chrome on iOS.

Based on your screenshot, it looks more like a (common) hardware issue. Though it is a bit strange if it differ between browsers (I assume you tested on the same machine).

"Vector tile layers have the best performance on machines with newer hardware."

Is your PC several years old? On an older PC in a meeting room my Vector Tiles were completely wacked with parallel stripes. So I remote accessed my newer PC and they then looked fine.

I have seen a somewhat similar problem while testing vector tiles. The tiles disappear at certain zoom levels - see attached zoning map image where there are large blank gaps. Vector tiles published via Pro 1.3.1.

In our case, the problem is evident on 3 browsers (Chrome, Firefox and IE 11) and on different PCs. Our PCs are anywhere from 2-4 years old (Win7, Dell, Intel Xeon 3.6GHz, 16GB RAM). I have not determined if it is a data problem, but at other zoom levels the tiles display fine.
