Hello.

Please use M-x report-emacs-bug, you still have not given us all info.
The #141414 instead of #151515 simply isn't happening here.  I checked all 
pixels, there are only #151515.

If you have another combination of colors, use that.
And describe each step clearly, starting from emacs -Q.

Thanks,

	Jan D.
