The dithering on/off never worked for me. My issue was with gradient alpha channel for creating shade effect. Your hint saved a lot of mine and my GUI designer's work hours (because we already started creating images without the alpha and with fixed backgrounds, then the stripes for the faked background fill ... what a nightmare) Keep it up ! Cheers, Tomislav Worked like a charm !

How would you go about doing that?

If that's the case, I can understand why dithering is recommended more often, as with 4-byte transparent color scheme, you'll need double the memory for the same bitmap. Otherwise, your approach should indeed be better than dithering. Cheers, Dimitar Hello, Eric,

Can you post some code snippet that works for you? I tried using Window.setFormat(PixelFormat.RGBA_8888) but I am still getting some banding.

If you don't have any gradients or images, you don't need it...but that would be a pretty boring app. I suppose it might be a good idea to check if the device actually supports it, and it could make painting slower.
