Have anybody same problem with polygons Soft Edge?

So, I have DVR crash in every time when I try to set Soft Edge more, than 0

Everything are updated

In what tool? Any tool, Power Window, Fusion Matte, etc?

(Soft edges work for me with Power Windows (including Polygon), a Fusion Polygon matte (which literally has "Soft Edge"), and in Edit's Crop inspector, for example.)

Sorry, on Fusion page with any polygons — Rectangle, Ellipse, Polygon — whatever

Soft Edges works for me in Resolve's Fusion (v17b9).
