If "glsl_correct_derivatives_after_discard=3Dtrue" f=
ixes it, it's not an
alpha-to-coverage issue. It's a problem with the use of discard in GLSL.

There is no difference in alpha-to-coverage behavior between DX and GL. Make
sure you have this fix:

it/?id=3Df222cfww3c6d6fc5d9dee3742d20aa77cfff9c39f8

If there is a difference between DX and GL, the GL specification can be
corrected or a new GL extension can be added for the DX behavior.
