In the shader log message, say if the error came from a PS or VS.
[Android] Things fixed in Qualcomm driver v53. GLSL Centroid usage. SHADER_INFO_LOG reporting 0 at all times. Some crazy nonsense that broke the FPS counter. Those are all fixed. glBufferSubData still makes the device do a OOM error, and is still stupidly slow to use. Many more bugs remain in this latest Qualcomm driver.
Work around AMD's broken Linux drivers when it comes to pinned memory and base_vertex usage. It seems that using pinned memory with base_vertex disabled is quicker than the other way around.
