Gradients w/o BGRA_PRE

What error are you seeing, or is it just rendering incorrectly?
Looking at the code in ES2Texture.uploadPixels() it looks like ES2 might
support BGRA via an extension. Perhaps we've only encountered platforms
with that extension so far. Otherwise, if I read the code correctly it
looks like we will just pretend the incoming data is in RGBA format,
which would mean that the rendering would happen, but the red and blue
components would be swapped. Is that what you are seeing?

But when I try to use a gradient, at some point PaintHelper.initGradientTextures() is called, which requires the pixel format BGRA_PRE Obviously something about my configuration is wrong. But I cannot figure out, where the alternative implementation resides. How should the implementation of gradients work if BGRA_PRE is not available?
