This seems to be an issue i've seen in the past with P3D and rotating clouds especially with Trackir.. as you turn your head with Sky Maxx Pro and cumulus clouds, they rotate.. really distracting. This doesnt happen with XE 1.04, but XE doesnt really use volumetric clouds.
I'm not sure if this is so much a FI bug as it is a bug in general with volumetric clouds..
Hoping there is a fix at some point.
