Chris, I git pulled the latest code today, and it's still causing segmentation fault running VMware on this commit. Reverting it solves the problem. Is there anything that can be done to resolve this in a proper way than reverting the code?

Do not try to fixup the alpha in the ff/shaders as this has the side-effect of overriding the alpha value of the border color, causing images to be padded with black rather than transparent. This can generate large and obnoxious visual artefacts.
