Does the OpenGL standard allow for some differencies between implementations in the way texture coordinates are treated, or is it safe to state that if the same patch with the same shaders gives different results (such as an image upside-down in either but not both) something is wrong in Gem?
it's a known issue. until this is fixed (i almost got it there, remember the thread on having to premultiply texture transformation matrices in shaders?), i suggest to use [pix_flip] right after your image source.
