Hello Doug,
I make in t7 a small test level with SKYDOME and I noticed visible artefacts when I move the mouse vertical up and down.
All normal objects with simple edges are deformed and you can see the deformation upon the screenshot.
I also noticed under ''script files'' at the display.c the gap of some functions, double names and wrong order, for comparison I made a screenshots of display.c with display00.wdl and marked the mistakes.
I compiled the test level through Publish, but after starting the myproj.exe it crashes immediately.
Have a nice day
