VSK Graphics Bug

If your game looks like this or similar, the instructions at the bottom may solve the issue for you.

Download DxWnd https://sourceforge.net/projects/dxwnd/files/latest/download (a tool for running various compatibility fixes for old games)
Unzip the downloaded file to a folder where you can find it again. DxWnd doesn't need to be installed, it can just be run.
Run dxwnd.exe from the folder where you unzipped it to.
