We spend quite a lot of time to find a workaround – unfortunately no success.
I could only recommend you to replace such translucent PNGs with transparent PNGs (have bit transparency mask instead of alpha channels), or GIFs or JPEGs.
If you have tons of images to convert, you may add on-a-fly image converter as a custom resource loader:

utilizing, for example, JAI library.
