RGBA(46, 46, 46, 51) can never be present in Image (it is invalid value).

I don't understand why it is invalid value since this value can be reached with iml designer ?
|
Ops, sorry, my premultiplied alpha info got rusted, in fact above RGBA is valid (but RGBA(51, 51, 51, 46) is not).
Anyway, I still think that this is the issue you are experiencing. And iml designer displays RGBA in "straight" unmultiplied form, which might be the source of confusion.
