Description

I need to copy to a new bitmap using ARGB_8888 config to get the correct image, otherwise the colors get really trippy

Research direction
Investigate the renderscript blur implementation in the repository, particularly the handling of different bitmap configurations. The workaround suggests converting to ARGB 8888 before blur. The fix might involve automatically converting the input bitmap to ARGB 8888 if it is RGB 565, or updating the renderscript code to handle RGB 565 correctly. Look at files like Dali.java or any RenderScript .rs files.
