Thanks for the report, unfortunately I have an android,, so for now I can't really debug it.
from sculptgl.
something wrong with me too.
when i // if (this._showGrid) this._grid.render(this)
the texture can not display correctly( look like color lump / color spot ).

This commit appeared to have broken the shader on some iOS environments.

Thanks, I suspect something wrong with shader derivatives, can you try https://goo.gl/m9C6Bx and see if it works?
from sculptgl.
yes, it work in my iphone5( IOS8.3 ) ( https://goo.gl/m9C6Bx ). seen like as desktop
from sculptgl.
Yes, it works fine in IOS10 Chrome. So if it means your suspect not established?
In my further test for SculptGL shader in IOS10 Chrome, I found PBR,matcap,normal shader are also not work well, but UV shader is OK.
So I guess the bug is from Reflection/Environment Mapping, pls check Jaume Sanchez's blog about Spherical reflection (or environment) mapping (SEM)
https://www.clicktorelease.com/blog/creating-spherical-environment-mapping-shader
Someone also report a bug in IOS8, and they solve the problem, but Jaume Sanchez's tutorial is base on three.js framework, I don't know if it work in native webgl.

I'm almost sure it's not the matcap shader as PBR and normal have the issue too.
It can be many things, but until I debug on an iOS for real, it's tricky to solve :p.

i came to ( https://www.browserstack.com/ ) test on IOS online within a free account.
it can test on locale need a plugin
i think it can help you

Ok I'll see if I can reproduce and if it's not too complex to setup!
