Hello Timothy (sorry for the double mail, email is a complex tool:) )

Hum, tbh. I was quite surprised to hit this bug. I guess you save a
pre-optimized shader in the cache. So it could depends on optimization
passes.

const ivec2 offsets[4] = {ivec2(...), ivec2(...), ivec2(...), ivec2(...)};

Strangely enough there are only 3 parameters without name in the
parameter list (signature is int, size 2 and CONTANT). Maybe one was
optimized away, I didn't look further.

Cheers
