This is the first I hear about what you say. So, this is somehow worrisome. Do you have ClearType on or off? Do you use ClearType default, initial setting? Are you using a color LCD display? Is the phenomenon still occuring in all/every ClearType Text Tuner situations? If you reset all IE10 settings to factory default, is there still a half pixel offset affecting test versus reftest ? > You could avoid the issue by replacing every two-letter > "word" with a regular block of width:2em and height:1em with blue or > black background.

I would prefer to have tests use real characters instead of block-boxes with colored background. Creating a reftest with Ahem font is doable but seems tricky at first for this particular test as you say. I would like to understand and first be sure of what could be affecting IE10.
