|same hatch - different appearance|
The funny thing was, that the properties of the hatch looked good - it got the right hatch pattern and scale assigned - but nonetheless appeared as "solid". Increasing the hatch scale helped to display the hatch correctly - but I didn't want to change the hatch scale.
It turns out that setting the AutoCAD variable HPMAXLINES to 10'000'000 solves the display issue.
