We're working on a STM32F469 with RGB888 and are seeing a lot of banding on bitmaps on the target:
The PNG files are smooth. We're using compression, but I am not convinced EmWi is causing this banding with its compression.
how did you configure your images? Please check the format of your bitmap resource and ensure that it is set to native and not to RGB565.
How does it appear within the prototyper?
Let me know....
If your bitmap does not contain any transparency, you can try to set the Format of the bitmap resource to RGB565 and use Dithering in order to get some error distribution.
Does this improve the resulting appearance?
