What is maximum image resolution for CompressedTexture based on renderer.capabilities.maxTextureSize

On Chrome Android, when loading a texture (KTX2, w=8192, h=2048 with alpha) the texture remains black and I get the console error:

ERROR :GL_INVALID_VALUE : glCompressedTexImage2D: dimensions out of range

It works fine on PC so must be related to phone’s hardware.

I am trying to understand how renderer.capabilities.maxTextureSize can be used to determined the limits of a CompressedTexture.

For example, when maxTextureSize = 16384, what are the maximum width and height of the compressed texture in pixels in case aspect ratio must be 4 ? And does it matter if the texture has alpha or not? The Android’s maxTextureSize = 4096.

Thanks for helping!
