Fullscreen is not centered using DOSBox-X (top cut off, black space on the bottom, and shifted to the left side)
These are the settings being used:

1fullscreen=true
2fulldouble=false
3fullresolution=desktop
4windowresolution=original
5output=openglnb
6
7aspect=true
8scaler=normal2x

These settings work perfect in normal DOSBox, but not in DOSBox-X.
This normally achieves fullscreen, touching the edges while maintaining original aspect ratios. It comes close to doing this in DOSBox-X, but as mentioned above, is off-centered.

It is occurring at all times, not just specific games or programs. It is noticeable immediately upon launching DOSBox-X (the blue background with the white border is visibly cut-off).
Nothing appears cut-off while in Window mode, only fullscreen.

Fullscreen (off-center):
download/file.php?mode=view&id=110827

Window (normal):
download/file.php?mode=view&id=110828

The host desktop is 4k resolution with display scaling at 250%. Not sure if it matters (didn't seem to effect normal DOSBox).

Any suggestions appreciated. Thank you.
