Hi Guido,

The rendering of line thickness in models/icons is a bug that we are working on. We have had an ongoing and previously reported issue of unexpected behavior with the general rendering of line thickness in Mathematica and its relative size compared to other graphical objects.

Similarly, as part of the development efforts of the upcoming release, we are reporting a bug related to text objects size, which is not always rendered as expected.

The output of SystemModel["model"] is a rasterized bitmap which is expected to be enhanced only by clicking in the plus icon on the upper-left corner.

Thanks for your input.

Sergio

Eric, I wasn't even thinking about a HighDPI-issue, since I am just working with FullHD resolution here? Is this about vector graphics as opposed to rasterized graphics?
