Major Graphics problem SSE

[LadycatSarah]

I'm having an issue with one of my mods where sometimes a sex scene will cause this to happen:I'm not sure what mod exactly is causing this, but I suspect Yiffy Age of Skyrim and Devious Devices, Most of these happen when I have a device on, though I don't in this screenshot. I do know that yiffy causes glitches around campfires and fireplaces that I haven't managed to catch on a screenshot yet: flashes of black polygons spiderwebbing across the screen and flashing in and out of view. I'd rather not uninstall Yiffy, but will do if there's no alternative.  I can deal with the fire problem, but not this. To be clear, this happens wherever, not just in this building, but not all the time. I've reloaded saves to fix this in the past, but this is the first time so far it hasn't worked
