(This isn't really a syntax question per se, but there didn't seem to be a better place to post it)

For some reason, I get different results when I'm using beginShape() with the default 2D renderer on an Intel (C2D) machine running Leopard, than when I use it on a PowerPC (G4) running Tiger.

I'm drawing a line made up of many points a distance of one pixel apart. When I run it on my Intel machine, it produces a jagged line, like so: http://dlpart.com/images/jaggy.png. When it runs on my PowerPC machine, it's nice and smooth, like so: http://dlpart.com/images/smooth.png.

What's going on here? Are there two different codebases for the PowerPC and Universal versions? Is it a Leopard/Tiger difference? Is this some bug that was later corrected? I'm using the 148 Beta release, rather than 1.0.

I'm aware that Tiger and Leopard are different, but that does not necessarily mean that the same program will behave differently between the two.

As for hardware, it's my understanding that the purpose of standard renderers such as Java2D are to mask the differences in hardware between any two computers, so one doesn't have to worry about the specific hardware configuration. Furthermore, if anything, I would expect it to look better on the more recent C2D machine. which has a Radeon X1600 (it's a late-2006 MBP), rather than the G4, which has a decrepit GeForce 2 MX (2001 Quicksilver), but it's the other way around.
