Sharpness of the dimensions in Creo 11

Hi

I have an issue with the visualization of the dimensions in the drawings in Creo 11.0.2.0.

The dimensions are not sharp like not perfectly in focus.

I have attached one screenshot with the same drawing opened with Creo 7.0.2.0 (left) and Creo 11.0.2.0 (right). There is a big difference for me.

I tried with another monitor with higher resolution and the result is the same.

Any one can help me?
