Can you give more details?

Yes, I just didn't know what would be relevant in a case like this.

In TrueType font 'gasp' table gives you control over grid-fitting and antialiasing at pixelsizes.
Probably your font have entry for sizes bigger than 30px with no-antialiasing flag.

Found it, but no... Plus it happens when I save it as otf also.

Is it systemwide, in some apps or just one app? (Assuming it is an installed font)

Found it.Many of my draft characters sat next to each other in one glyph, and that's what's been pissing fontlab off. 10x anyway
