Trying to run VarAC on Pi 5 with Wine + Box86 + Box64

I'm trying to get VarAC running on a Pi 5 running standard Raspberry Pi OS with latest patches.

FWIW, I have Winlink + VARA (HF and FM) working very well in my current configuration that consists of:

WINE (with winetricks)

Box86

Box64

I've tried it with Linux mode enabled and disabled with the same results. Same for Advanced mode.

I get a screen open with most of the fields blacked out, as you see below.

(Note, I'm remotely connecting to my Pi 5 using NoMachine.)

Any tips would be appreciated.
