This sounds a bit like a blitter vs. video memory problem. Maybe XFree86 is overclocking your graphics chip. But since it happens only with mozilla that's not very likely.

gecko has various macppc-specific problems, I get misplaced text with wrong attributes all over the place, but no horizontal lines. Only with applications that use gecko so I'd suspect a bug ( or some wrong assumptions ) in the PowerPC-specific part of XPCOM but that's a hell of a beast to debug.

Not really. For some people it helped to update X from sources or to recompile mozilla though.
btw. Konqueror doesn't have these problems.

have fun
