What happened?

With the Windows 3.1 Video 7 VGA driver, the Radius SVGA Multiview, which uses the same Headland chipset as the Video 7 VGA 1 MB and worked with this driver in previous builds of 86Box displays completely corrupted display, aside from the mouse pointer.
I expected it to work correctly, as it was working before (both on Windows 3.1 build 34f and RTM as well as Windows Chicago build 07200022)
