Something goes awry on the texture decoder.

Verify Failed : w==h || !tcw.MipMapped in Create -> ../../core/rend/gles/gltex.cpp : 217

It looks like it sends some invalid texture configurations, which are most likely ignored on the real hardware.

It sends a non-square mipmap texture, and a a texture w/ VQ enabled. In both cases we verify, which can lead to a crash or an error message. We need some better way to collect this kind of 'validation' data, as it is really useful when debugging random crashes or stubbing out functionality.
