[Bug] Cursor not positioned correctly?

I'm wondering whether this is worth mentioning or if it's already a known issue but I've noticed it fairly often.

I've been having issues with the cursor not being correctly place to where I'm actually clicking, I don't really know the better term for it but on the odd occasion I've accidentally attacked a large unit even though I've clearly clicked on a tile either adjacent or even further away.

Also a quick note is that I'm running this at 1920X1200, and I've noticed the text is quite small in some menus including the MP menu.

Also had a significant bug involving Hedge walls and the fortress walls.

Upon completion of the fortress set-up I demolished the hedge walls which left me without any walls around my city.
