Problem with textures non power-of-two size (v4.3.0-alpha3)

[Yason83]

Windows11 + v4.3.0-alpha3
ktx create --format R8G8B8_SRGB --encode basis-lz --clevel 5 --qlevel 255 TeakVeneer_2K_albedo.jpg TeakVeneer_2K_albedo.ktx2
produces unpredictable effects when loading textures with dimensions that are different from a power-of-two size.
In the case of the "TeakVeneer.jpg" texture, no errors occurred, but the texture was not created.
In the case of the "TeakVeneer_512x510.jpg" texture, no errors occurred, but the texture was distorted.

It would be logical in both cases to either display an error indicating that the texture is not supported or correctly convert it.
