--- Comment #6 from Adam Strzelecki <ono at java.pl> ---
Sort of. It looks like before r172008 all text box offsets were rounded to device pixel boundaries, but the r172008 introduced rounding only in one direction, so when text is horizontal only Y is rounded, when vertical only X. I completely don't get the reasoning behind that. But the result can be observed on attached sshots.

I only hope this is THE change that caused the bug and no other changes were introduced afterwards, this is just because I did bisections using last years nightly builds, but there is a gap between r171989-r172326, so I blame r172008 just looking at the changes between these releases.
