I did a 'git bisect' between 1.12.3.901 and 1.12.4 and the following commit seems to have caused this behavior:

"fb: reorder Bresenham error correction to avoid overshoot."

For what is worth, the issue is present with Catalyst 12.6 Legacy on my desktop machine, but not on my netbook which uses the xf86-video-intel 2.20.5 driver.

Also happens with the NVIDIA driver but not with Nouveau. [1]
