The issue hasn't happened again today, although a slightly different looking crash happened on returning from testing a different time. Unfortunately, I clicked the wrong button, so I didn't copy the error dump.
Resource Monitor currently looks like this:
I haven't actually restarted since the crash.
Pretty sure that I have the correct version of SlimDX installed.
FWiW, I went from GZDB32 to GZDB64, found some problems and so went back to 32 bit for the moment.
In other news, I just wanted to check whether this problem is known about (I think it is, but if not, I'll post on github).
Complicated slopes using things don't render properly in Visual mode.
Here are some screenshots using a UDMF converted version of Randi's original slopes demo wad. I converted it to UDMF because I was using some very similar constructs in a UDMF map of my own when I noticed the problem. The UDMF version shows slightly more weirdness than the Hexen version in visual mode, but neither work properly.
In game, it looks fine:
When first going into visual mode, the UDMF version looks like this:
I am aware that there is also an issue with slopes that copy their plane from another slope and that hitting tab twice to disable and re-enable enhanced mode fixes things, but in this case it makes it weirder.
I think this one looks right:
But the others, not so much
