you can also see it in another way: if you look at the menu in the off-image (so on for menus), you see that the shortkeys (strg+n, etc.) are not aligned.
anyway, these are images. they should look the same on every monitor. except colours of course. maybe i get distracted easier then you, because of being a perfectionist.
but you could test it yourself. change your cleartype settings in a way, that they DON'T look good. then turn cleartype on and off multiple times to see that different GUI-items seem to invert the settings.
anyway. my goal is not to make it look good on my machine, but to report the initial problem, namely cleartype not being turned on or off completely. there is probably just a boolean-bug somewhere in the code, that inverts the settings. just a quick guess
