It shows coordinates from last screenshot (F3 Debug). I also communicated this with mods on Discord and it's okay to use (it's not touching the game at all) but if there are any mods here that don't agree please let me know.

STL 1.2 It now supports all of the GUI scales, all of the resolutions and all of the game versions above "release 1.0", you don't have to change any settings, it will analyze the screenshot and check how big and where coords are.

STL 1.1 It supports all GUI scales now, you can right-click on the window and change settings like GUI Scale and cleaning your "saves" folder with CTRL+O.
