Traced the issue down to the addition of tiling support. There was some old code that would only paint the tile if the tile was bigger than 1x1. Quite a bit of work has been done to tiling and I don't think this rule is valid any more. The else for this 1x1 or greater case was to use the most recent fill colour which in this case was black. The update appears to fix the PDF in question. the the white png tile is now painted correctly.

Took a quick look and the issue is related to pattern painting. The black boxes are painted behind the text using a tilling pattern paint. Its the paint that is causing the problem. Because the pattern paint is coming out black instead of white the black text is no longer visible. Should be able to fix this for 4.3.3.
