1:1 partial screen shot showing color where there should be gray only
When first seeing this I thought it's an artefact of my LCD monitor (which has very high display quality), but after taking a screen shot I found out it's the application, not the display:
Some black characters seem colored at some zoom levels. IMHO that's a usability no-no. See screen shots (one regular size, one zoomed for clarity).

You probably wanted to say: It's not a bug, it's a feature. See "ClearType, 2014. Wikipedia, the free encyclopedia [online], [Accessed 12 May 2014]. Available from: http://en.wikipedia.org/w/index.php?title=ClearType&oldid=606198945. Page Version ID: 606198945":
"Like most other types of subpixel rendering, ClearType involves a compromise, sacrificing one aspect of image quality (color or chrominance detail) for another (light and dark or luminance detail)."
