IPR and VrayVolumegrid - not working properly?

[caypiranha]

Hi Guys,

I am having a VDB / VrayVolumeGrid here. As soon I turn the Viewport, IPR stays black. Editing Values are IPR fine, but navigation and also FB´s Real Zoom isn´t working and remains instantly black
While hitting the refresh button, IPR restored again. So I assume, that there is only a refresh problem? Maybe only here by me.

Yeah, it's a refresh issue. I've logged it (internal bug-tracker id: PHI-6654) for developer investigation.
