Instead of using set_alpha(), try using a fill, like: backgroundsurface.fill((0,0,0,100))
that should make the background use per-pixel alpha too, since there's a fourth number in the color (for alpha) so blitting another per-pixel alpha image shouldn't cause problems. Hmm... maybe I'll try it out too. -Lee- On Thu, Apr 22, 2010 at 12:46 PM, stas zytkiewicz <stas.zytkiew...@gmail.com > wrote: > On Thu, Apr 22, 2010 at 6:56 PM, Lee Buckingham > <lee.bucking...@gmail.com> wrote: > > > As far as the alpha goes, my guess is that you're getting hung up because > > you've mixed two different alpha modes.
