Link to problem discussion in GM discord

When using window_set_position(0,0) immediately before or after a window_set_size call, the position is not correctly set, instead appearing at (0,25)

If i call set_position 1 frame after, it works as intended. Another user tested in discord and did not have this problem, which leads me to believe it may be machine/windows dependent. (im on win10)

Steps To Reproduce

set_window_size(display_get_width(), set_window_height(display_get_height()-50)
note: -50 should be whatever your taskbar size is

then set window_position(0,0).

This is legacy behaviour that we cannot currently change, as various games will depend on it.
It should be documented.
