Yeah, Mala transparency kinda stinks. It supports PNG, but not the alpha channel, so you can't have smoothly faded transparencies, which means you'll always end up with jaggies on rounded (or non-square) masks.
I'm actually trying to come up with a solution for that in Engine18 (an addin for Mala I've been working on), but haven't quite got all the kinks worked out yet.
Love that layout though. That kind of layout would work well with my slideshow plugin (basically, it rotates through various images associated with a particular rom with a little animated fades for good measure).
I'm not quite done with that either though. Pesky things like a job keep getting in my way
