ATI HD 4830 in perfect mode - landscape missing (black)

[CRO_Ante]

I have really strange problem in IL-1946, when I enable perfect landscape I got blackness instead of landscape.
I've tried different versions of Catalyst 8.10, 9.4, 9.2 (A.I. disabled) and always same problem. When I lower landscape details from Perfect to Excellent, landscape becomes visible.
