Crash on DX11, 2.0 under certain specific conditions

[ideka]

I'm using 2.0 RC3, and this doesn't seem to happen on dx9, only dx11. I haven't exactly pinpointed the conditions that trigger it but I was able to reproduce the crash fairly consistently with the following steps:

1. Join a friend's party (or use an alt account), and enter Fractals of the Mists (I entered from Mistlock Observatory, assuming entering from LA makes no difference)
2. Go inside a fractal (I think any would work, but you need one where it's fast to generate a combat event from spawn; I used the lava river in Underground Facility to test)
3. Close the game, leaving your friend alone in the fractal
4. Reopen the game, then as fast as possible, login to your character, enter the fractal, and generate a combat event (jump in the lava river) -> crash

It seems that if you don't do it fast enough the crash won't happen. Also I couldn't trigger it in the open world, not sure how fractals are related but that's the only place I've had this happen.

Here's a crash log. Note I was using a couple more arcdps addons, but this happened with just SCT, too.
