Problem
In the Windows port, the '@' representing the PC flickers when attacking an enemy, waiting in place or 's'earching, if you have ClearType enabled.

How to reproduce it
Given the above conditions, try to attack a monster, or press 5 to wait one turn. Notice how the '@' representing your character flickers when you perform either of these actions.

Notes
This might be related to the new drawing code, as it doesn't happen on Pr5 or 1.1.1.
