I did a fix to the repo if you want to try it out, now the when using vertical scanlines integer scale set to 1 will only integer scale the horizontal, and the vertical will be whatever it needs to be to keep the aspect ratio. Then if you set integer scale to 2 it will integer scale both horizontal and vertical.
Just a note about the repo, I can only vouch for the STD and ADV, and SMOOTH-ADV GDV presets working at the moment, glass seem to be working too
