Final Fantasy 12 Target Lines

[Rafae]

Now I'm not sure if it's a glitch or not, but PCSX2 seems to make my target lines go weird.

Half the time they're yellow, but sometimes my attacks are making red lines instead of blue too.

I know it's a minor glitch, but it's somewhat offputting considering they work properly on my PS2, does anyone know how to fix them?

EDIT: I've got PAL Version, if it helps.

Check the Allow 8bit textures option in the GSdx config.

That just broke some textures for menus and HP/MP display.

On my PC the party menu seems to be laggy with 8-bit textures. But when it is off it has no lags at any resolution ?
Why so ? And please tell how to resolve it..
