Game gets stretched when aspect ratio is not 4:3 or 16:9

[BlueNoBaka]

When the game resolution is set to values not 4:3 or 16:9, but like 21:9, by editing command line.txt, and in full screen, everything seems to be stretched from a 4:3 resolution. (Characters are shorter and fatter in 21:9) If you runs the game in windowed mode, the 3D part will be rendered properly, while the 2D elements still seem to be stretched, such as the phone and websites. Actually, even in the 16:9 resolution, the 2D elements are stretched comparing to the 4:3 one.
