Fill layers don't render on some devices

[ljbade]

I just noticed today that on my Windows 8.1 machine random tiles are rendered blank.

The tiles jump around a bit as I zoom in and out.

I am using Chrome 39.0.2171.95 m

My machine has both Intel and NVIDIA graphics (not sure which one is used by Chrome).

Any errors in the console?

My guess would be network errors. If it fails to download a tile it just doesn't show anything. Should it do something different when downloads fail?

[ljbade]

@ansis no console errors.

Also I don't think it is download error as native has no issue on this computer and is very repeatable.

Tested Windows Firefox, same problem.

Can't test on IE.

Doesn't happen with either Chrome or Firefox on my Linux machine.

@ljbade Is this still reproducible with 0.8.1?

I don't know if this is the same error, mapbox-gl works correctly with Chrome and Firefox on Linux but seems to be broken on Chrome and Firefox on Windows 7. Internet Explorer seems ok on Windows 7. Looks like only certain layers not visible, on the Mapbox example page and on my application.
Chrome Version 43.0.2357.130 m
Firefox Version 34.0.5
Note my app uses ver. 8.1:

Here are some screenshots

@glennerichall are there any errors logged in the firefox and chrome consoles?

+1 on this issue. Several of our clients are experiencing the same thing. We currently embed Mapbox inside a .NET client app using Chromium Embedded Framework v39.0.1 which uses Chromium 39.0 under the hood. Every client using Windows 7 is experiencing the same issue.

Windows 7 using CEFv39.0.1 & Chromium 39.0

Chrome on OSX (No embed, just in browser)

I haven't seen this issue first-hand yet and only have screenshots. I'll take a look in the console to try and get more information.

Just to add additional information that may be relevant to troubleshooting this issue.

Initially the problem was sporadic and we were not able to replicate the issue in-house using CEFv39.0.1 on Windows 7. (CEF being Chromium Embedded Framework) MapboxGL worked perfectly.

Recently we updated CEF to v43 and suddenly we could reproduce the bug. I also noticed dropped tiles in the GL examples at https://www.mapbox.com/mapbox-gl-js/examples/.

We were only able to reproduce the issues in the more recent version of Chromium.

Not sure if this is the same core issue or a different one. I've been seeing problems where some of the the background colors of various styles is different per tile. For example, from "A simple map" (make sure you click on "A simple map") I see this:

This broken result is consistent for me across Chrome (v45.0.2454.101m), Firefox (v41.0) and IE (v11) on Windows 7x64 with a GeForce GTX 670 graphics card and the current driver (v355.82, released 2015-Aug-31).

@jfirebaugh Do we have a Windows 7 machine we can repro this on?
