v6.0 BUG - CFractal in Full Previz X10 times slower.

Hello,

as in the title, CoronaFractal in Full Previz X10/15 times slower in v6.0

() Create an empty scene
(
) Create a default CFractal
() Change Previz from Sphere only to Full
(
) Change Resolution mult: -2

With v6.0 it’s impossible to move the viewport (0.6 FPS).
With v5.0 I have 10FPS (it depends on the zoom level)

GPU = 1060

Thank you
