Re: QPainter: painted color (brush) and pixel value (read after the draw) are differ
do the values only differ in one bit?
I am surprised they are at all close!
QPainter::drawRect() does not fill the rectangle, so position 50,50 (middle of your rect) must be different than the outline which QPainter drew with drawRect() - or am I missing something in your post?

Do you write clean code? - if you are TDD'ing then maybe, if not, your not writing clean code.
