Somewhat long time user here. I was messing around with a model that
involved subtracting a primitive with an imported .stl I know this isn't
recommended, but I figured I'd give it a go.
Problem 1 is that Openscad is crashing on render because windows registry is
timing out the job to the graphics card. I think I know what to do here
because I can edit the timeout for graphics card jobs (default is 2 seconds)
and run it.
Problem 2 is that somewhere along the many restarts and crashes This

fix. Uninstalling and reinstalling fixes it temporarily but as soon as you
edit a file it breaks again. It's a rather strange error in the text
display, I can keep using it like this but it's pretty ugly.
Little embarrassing but I figured i'd update. Turns out I was having a
problem with a file crashing on open because of the GPU timeout problem. I
opened it in word-pad and added two \\ characters in front of the import
statement. This seems to have caused the display problems. I guess openscad
doesn't play nice with other text editors, good to know.
