Hi Sean, It seems we do not support API clCreateFromGLTexture in beignet, you can get what api we support from the file src/cl_khr_icd.c. If PyOpenCL can run into this maybe there is something wrong with the device extension check either for them or for beignet. I will recheck about this and give you a clear reply then.
