Description
Using "large" 3D objects to render a lot of points in 3D will start eat up memory (attached image).
When all physical RAM is consumed, it continues with virtual memory. When this also is consumed the computer becomes unresponsive.
I'm using a 6 Mb *.obj file from https://free3d.com/3d-models/ and a point layer with just 500 points. Turning textures "off" helps some, but doesn't fix the problem.
It's a bit of a "fringe" use case, but the software should not allow the computer to become unresponsive at least.
