hi-
that could be down to a couple changes i made to the config (dosbox-staging.conf in the same folder as wordhopper.exe). first thing to try would be the line starting with "output", changing the value from "opengl" to "texturenb". if that doesn't work, on the line starting with "glshader", change that from "interpolation/sharp" to "none" (in addition to the previous change). if neither does anything, worst case scenario the config from v1 should still work with v2 (if you've still got it)
sorry for the inconvenience.
