I'm trying to use transparent png's in most of my skins, and often getting problems when I use a transparent png over a transparent png (i.e. as in a picture.png over bg.png).

For example:

See the jagged edges around the LED? It looks like most of the problems seem to be with portions of png where I'm using alpha channel transparency. Any tips anyone?

I've reproduced the bug. But cannot understand why this problem appear. What do you use to create PNG?

I've found the possible problem. The resolution of you file is 200 pixels/inch if I make same 72 pixels/inch then all works file. 72 pixels/inch is screen resolution and TLB to not have STRONG algorithm for resizing PNG's.

I've attached modified PNG.
