Describe the bug
Each time you start the machine immediately in full screen mode (86Box.exe -f), the window coordinates decrease by 2. For example, initially in the 86Box.cfg file there is a line: window_coordinates = 412, 31, 1736, 1292. After starting the machine immediately in full screen mode, the window coordinates decrease by 2: window_coordinates = 412, 31, 1736, 1290. That is, the number 1292 became 1290, the next time the machine is started immediately in full screen mode 1288, the next time the machine is started immediately in full screen mode 1286, the next time the machine is started immediately in full screen mode 1284, etc. That is, the window coordinates are not saved when the machine is started immediately in full screen mode, and each time the machine is started immediately in full screen mode, they are reduced by 2. This bug appeared in build 4202 and persists until the last build. In build 4201 everything works fine.

Expected behavior
Each time you start the machine immediately in full screen mode, the coordinates of the window should be saved.
