Try setting environment variable GDK_USE_XFT=0 before starting 

You can also create a ~/.fonts.conf file or edit the 
system-provided one and add this:

<match target="font">
    <edit name="antialias" mode="assign">

I've not tried the second one (found on Google) but the first 
works for me (but only w/ system GTK, not private GTK).

Possibly not surprizingly the snapshot looks fine on my laptop -- 
I've seen this before that some LCDs just act differently.  You 
might Google a bit on antialiasing, possibly to control
sub-pixel rasterization.  From http://www.xfree86.org/current/fonts2.html
I found:

"""Xft supports sub-pixel rasterisation on LCD displays. XFree86 
should automatically enable this feature on laptops and when 
using an LCD monitor connected with a DVI cable; you can check 
whether this was done by typing

$ xdpyinfo -ext RENDER | grep sub-pixel

If this doesn't print anything, you will need to configure Render 
for your particular LCD hardware manually; this is done with the 
following syntax:

<match target="font">
    <edit name="rgba" mode="assign">

The string `rgb' within the `<const>'...`</const>' specifies the 
order of pixel components on your display, and should be changed 
to match your hardware; it can be one of `rgb (normal LCD 
screen), `bgr' (backwards LCD screen), `vrgb' (LCD screen rotated 
clockwise) or `vbgr' (LCD screen rotated counterclockwise)."""

Not sure that's relevant for your case but I messed around with 
that at one point on an older laptop and it helped.
