Assassin Djinn's Portal Bug

Getting graphic lockups while using Assassin Djinn's Portals. Seems to only happen while using this portal. I turn the portal effect on and usually within 15 minutes and the screen will stop for a second and an AMD driver report pops up.

I am only having it with this specific portal, running a 9070 Hellhound in my PC. The first crash was bad enough to have to restart my computer because all the monitors stopped working.

Since then, they are seeming to be handled better with just a second pause and then driver error thrown.
