I thought that this bug had been fixed but still in version 37.0
I have a resolution of 320, 240 and letterbox integer scale activated.
If I increase the NWJS window to twice this resolution (640, 480), the game image does not fit the window.
Resolution: 320 x 240
Letterbox integer scale
When using letterbox integer scale the image of the game should be adapted to the window because it exactly matches its duplicate resolution.
The result is not correct
