When Im editing in the maps section in the dev panel, the highlighted block doesnt seem to be aligned with where my cursor actually is. Heres a cropped screenshot:

I put a red dot where the cursor is.
The issue seems to get worse as I head towards the lower right of the screen, and is less of a problem the closer I get to the upper left. I doesnt even seem to be a present issue in the upper-leftmost square.
I saw some threads on here talking about this kind of issue happening if you follow a tutorial on the touchofdeath forums, but I didnt do anything like that. Its behaving like this right out of the box.
