Steps to reproduce the problem:
1. loading image is larger than the maximum WebGL texture size.
2. resize loading image down to the maximum WebGL texture size 
(to be able to use it as single texture)

What is the expected behavior?
The image is resized normally.
And can be mapped correctly.

What went wrong?
Loading image is broken by resizing and it can not be mapped well.

Did this work before? Yes Version 53 or earlier

Does this work in other browsers? N/A

Chrome version: 54.0.2840.85  Channel: stable
OS Version: 6.0(Xperia Z5)
Flash Version: 

This problem occurred when using Krpano. 

http://krpano.com/
(krpano Viewer create panoramic images from equirectanglar image)

I contacted Krpano Support, And they replied below.

> It happens when the image is larger than the maximum WebGL texture size.

> E.g. your image is 5376x2688px large but on Android the typical maximum 
texture size is 4096x4096px - and krpano resizes the image down to 
4096x2688px to be able to use it as single texture (<sphere> images are 
only supporting single textures).

They taught me there is a problem with resizing the image.

Have you reported similar problem already?
