Group rotation not working in iray viewport

DireWorks

After the last update, when i use groups in large scenes, the rotation of some object works in the opengl viewport but it does not rotate correctly in the iray viewport, ofc there are many nested groups but it always worked in the oldest version.

If i try to render (same size of the viewport) it gives me the out of memory error, when i move back to viewport, iray start rendering again, same rotation error. Did i miss a new feature about groups usage?
