Describe the bug
Example: when the terraform tool is open, your company window is open, and your mouse cursor is pointing at the viewport in the company window instead of the main viewport.

• When the company window is in the top-left quadrent-ish of the screen, the highlighted land tile will be offset from where you are pointing the cursor, to a degree that gets worse the further the company window is from the top-left corner of the screen.
• When the company window is in the bottom and/or right halves of the screen, the terraform tool will no longer highlight a tile. (The cursor position is so offset that it exited the bounds of the company window viewport?)
  • Using the terraform tool will apply changes to the last tile that was highlighted (does not apply to other actions such as planting trees or clicking vehicles/stations/towns/buildings/etc).

Also applies to other windows such as vehicle windows, and other tools and actions that are done by clicking on elements of the game world.
