I use our in-house J2SE tool-kit to create a picture with a transparent background (fill the background with black color and turn Alpha chanel to max) then import it to game.
When I test the imported picture on N95 (S60 3rd), some times (not all the time), I get some black area instead of transparent background.
I can only reproduce this issue on N95, my S60 1st and S40 5th display PNG files correctly.
I'm thinking maybe it's a pb of numbers of color?
Any idea? Thanks much
