I'm currently in the progress of writing a simple WebGL application, where multiple textures are blended on top of each other.
我目前正在编写一个简单的WebGL应用程序，其中多个纹理相互混合。
The application works fine in Chrome, Firefox and IE on Windows, and also works on Android phones.
该应用程序在Windows上的Chrome，Firefox和IE中运行良好，也适用于Android手机。
On Apple devices, however, the textures are red and flickering in any browser. I tested this on Safari on iPhone or Chrome and Firefox on a MacBook.

There are no errors and no warnings from WebGL. What could be the issue or a hint to the issue here?
WebGL没有错误也没有警告。这个问题可能是什么问题或暗示？
