@igh08191 please attach the offending project+data. Also try with a new QGIS profile.

Loaded two vector layers, one a LINESTRINGZ and the other a POINTZ.
Both given a 3D symbol. with elevation set to Vertices and absolute.
This maps fine with in the default 3D view. I can zoom and pan all I want. it also works on both my screens.
One driven by NVIDIA Quadro M1200 and the other Intel (R) HD Graphics P630.

I add a dem raster and this works fine on both screens.

I then go into the 3D window attributes and set the terain to the dem and on accepting this change, QGIS crashes. This happens every time.

The 3D window also has trouble with the number of points in the vertices layer.

Below is the trace from the attempt to check with the smaller dem. my real dem is too large to post, even after compression.
