Hi there,
@Dr. Venom:
I think i found the glitch, a matrix had an error, i fixed it now and checked other matrices too, should be legit now.
Could you test this version? Hope we don't have to revert...

Bad news here, the shaders in the preset work as an interlaced composition of effects and calculations which require a proper meta-environment currently only Retroarch and maybe Bsnes can provide. But you could try to port the crt-trinitron for MAME, it's a single pass GLSL shader...
