I am just upgraded to the new libs and am experiencing a problem with alpha channel of bitmaps coming from an SWF:
before the upgrade the result was this
after upgrade I have this
The original image is a MovieClip set to render as a bitmap from the Flash IDE, but the initial image doesn’t use any kind of alpha channel for the red and black areas, I wonder why the SWF “exploder” is now generating a bitmap with those pixels invisible.
In the changelog I have seen a few lines regarding alpha channel, I think something didn’t go as expected…
