User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/600.3.18 (KHTML, like Gecko) Version/8.0.3 Safari/600.3.18

Steps to reproduce:

Visit: https://www.blend4web.com/apps/webplayer/webplayer.html?load=../../assets/interactivity/solar_system/solar_system_en.json&v=20150326165850

The background galaxy texture is omitted. This is just for Firefox (and also Nightly build) for OS X with Intel graphics card.

The problem is the background texture does not load.

I am using Firefox version: 36.0.4
I am using OS X version: 10.10.2


Actual results:

The background image does not load.


Expected results:

There should have been a background image.

This is the bug you mentioned yesterday, right Jeff?

Seems to be working in Nightly46

Seems to be broken again!
Using :
- FF 47.0.1 (also true with latest Nightly version)
- Mac OS 10.11.5
- MBP 12.1
- Intel Iris Graphics 6100

This page: https://www.browserleaks.com/webgl gives me only 512 for the "Max Cube Map Texture Size" property and I cannot play this panorama: https://pannellum.org/documentation/examples/cube-map/

For the record, Chrome and Safari give me 16384 for the "Max Cube Map Texture Size" property.

We've had, and still have, a 512 limit on the cube maps on Intel.  So, if this bug is to remove that limitation, then it's not resolved fixed.
There are no limits for cube map on other vendors.

Arthur, to test if we're talking about the same thing - set gfx.work-around-graphics-bugs to false (in about:config) and restart Firefox.  You shouldn't have the 512 limit at that point.  Can you confirm?

I think we're definitely talking about the same thing: 512 limit on cube maps size.
However, setting the variable and restarting Firefox didn't fix it.

Let me know if this is still a problem, but it works for me!
