NOTE: The issue seems to occur when the camera is rotated. You can see from the movie that the camera is very slightly rotated since the rulers are hidden. Even a very slight rotation appears to throw the picking algorithm off.
The camera can be reset by selecting Realign Camera from the View menu, but it is quite easy to get into this state by mistake.
Expected behaviour
Placing a tile where I click
Actual behaviour
Tile is placed about 70+ blocks above where I click
Steps to reproduce
I have no clue, but it's done this to me twice now. Restarting seems to fix it.

Ah. Good call. If I see that happen again, I'll give that a shot.
