I copied geometries, wich were created in grashopper, from an existing file to an other one. In the first piture you can see the geometry the way it should look and the second one is the one with the visualisation issue.
I guess it is no hardware related issue but i updated the graphics card driver anyway, but any improvements happened.
Does anyone know how to solve this?
Btw, is there something similar to reduce mesh command for polysurfaces? Even that could be the issue, as it was inserted in a heavier file.
