The compatibility is fixed on the new version 3.2.5. There is a new plugin parameter called Visu Core Engine Battler Name Compatibility. Set this to true and the Actor name will be drawn with the Bitmap font.
Because of the obfuscation, I don't know what is causing the problem. I guess that there is something to do with the Sprite_Name.prototype.redraw function. Somehow Visu changes it to draw the name in a different way. What I did was, just restore that function to the same as the original RPG Maker code uses. Don't know if this will cause any issue, probably not, it's just how the Sprite_Name is drawn. But don't know if other visu plugin uses that.
