This is a regression from commit https://github.com/doitsujin/dxvk/commit/7df8017e46692e972c710435261950c941b03acd
The as of writing current version of PR https://github.com/doitsujin/dxvk/pull/4036 improves it so it is only a bit over half the ground that is black, like seen above, versus more than three quarters of it on the regressing commit.
