OpenSCAD too slow to display geometry (under linux)
I'm running 2017.11.10 under Ubuntu 18.10 and I created a model that can be
rendered in a few seconds, but cannot be displayed my OpenSCAD on my linux
machine. CPU utilization remains at 100% and the program is non-responsive.
If I use the command line I can generate an STL file and load the model into
slic3r and view it without problems---slic3r reports that the model has 9248
facets. OpenSCAD says the CSG tree has 41561 elements.
Is this normal/expected behavior? Or is this a bug I need to report?

That's interesting. So it appears the problem is a quirk of the preview
algorithm. The page you referenced doesn't give the fix to this problem: I
wrapped my model in render() and now I can view it without difficulty in
