RunInUAE X5000 Scanlines

Hey guys, I've been scouring the internet for someone who might know if there are more options to get better scanlines in UAE on the X5000. I'm running EUA and the only option in the config that I've seen is this:

gfx_linemode=scanlines

Which gives me giant scanlines that dim the picture and does not look very good. Does anyone know if EUA is capable of doing shaders or any other scanline tricks to make it feel more authentic? Thanks in advance.
