WebGl error on isVisible change in webview

[Hersir]

Hi,

have weird issue on android webview (Note 8, Android 7.1.1)

Have meshes, that are clones of 1 mesh, with different materials (PBRMetallicRoughnessMaterial).

These meshes have 2 states enabled and disabled, and each state have different baseTexture.

Also these meshes are set visible and hidden using isVisible.

When state changes to enabled, texture is changed on material and isVisible is set to true,

all works well except in android webview, where such error is thrown and mesh is transparent.

If mesh visibility is not changed (all are visible all the time), there are no error.

thank you for any hint

There must be a previous error as these ones are just consequences of the first one

Just in case, can you try to set engine.disableTextureBindingOptimization = true (right after creating the engine)

@Deltakosh Hi, thanks for hint, looks like `engine.disableTextureBindingOptimization = true` fixes issue, as it not repeating any more.

Also it fixed this issue as well
