If you want a confirmation about something then you should define the
differences.

A quick look shows some different colors. However you're using alpha for
those colors and the form's background color is different in the two
screenshots (which can explain the end result difference).

In doubt always fill a bug report, including a test case (like this one)
and a description of what is, in your opinion, wrong (missing). If it's
not a real bug then it will be closed (with a comment why).
