Re: [Public WebGL] Recently fixed bug in ANGLE glUniformMatrix
Are you sure that is a ANGLE bug and not a Firefox bug? Because we fixed a very similar bug recently in Mozilla code.
The conformance test for uniform arrays of length 1 is
We used to fail it when we had the bug, so I consider it to be complete enough.
There was a bug in ANGLE's glUniformMatrix implementation as
recently as version 963 that is fixed now. The bug was that a call
to UniformMatrix4f with a count > 1 for a variable declared
with, e.g., "uniform mat4 my_matrix;" would incorrectly cause
GL_INVALID_OPERATION to be raised. Excess data is supposed to be
ignored for arrays.
Is there now a conformance test for this? Since the problem has
been fixed, I'm guessing there is.
