yes the RGBA channels are set wrong on mac osx. the cube appears blue because the alpha channel is read as blue.
when you change channels like this 
R –> G 
G –> R 
B –> A 
A –> B
the movie will justified. but it´s not handy to give each record this process so  
i fixed this with a change in the code of recordQT.cpp in line 241 - instead of colorspace = k32BGRAPixelFormat;
i use colorspace = k32ARGBPixelFormat;
but i don´t know how this affects other os

also the recorded mov is upside down - this can fix in quicktime pro with a click in the properties of the video track -
so i don´t looked for the code issue.

That way, for example, someone who doesn't have the OS required to run the bug, can still fix the bug by just looking at the screenshot. But this requires an example with enough different colours... just grey is not enough. For example, this picture :
