You may want to play with aliasing controls for font rendering.
I need to look into this (fonts) but hoped the problem is elsewhere.
Perhaps your monitor doesn't have the traditional RGB (red green
blue)
pixel grouping? It might be in BGR sequence (your photo looks like that from the
defocused blurs on the green text).
I still do not see why placing an windows at an odd x is different from an even position.
Moving the image changes between these two displays with each pixel shift.
BTW this is what the pixels look like:

Looks like BGR left-to-right? Should that matter?
Still, using 'xmag' shows a nice text without any artifacts, so I wonder if this
is an issue
with the actual monitor (TV) - assuming xmag grabs pixels from the screen not knowing how
they were painted (e.g. a font renderer).
