VW18 - Odd redraw glitch?

[Chuck Davidson]

Howdy folks;

Been a VW user since it was called MiniCAD.

iMac, Late 2014

High Sierra v10.13.6 (17G65)

4 GHz Intel Core i7

32 GB 1600 MHz DDR3

AMD Radeon R9 M295X 4096 MB

 

We are on 2018 architect, and have been experiencing a strange glitch with larger models of a +200mb file size. When changing wire frame views the whole model becomes invisible. Sometimes it'll come back with command-5, sometimes with render to OpenGL. Sometimes it won't come back at all.

 

Below is a screenshot which shows the model components still present as highlighting when the cursor rolls over them.

Searches in the Trouble-Shoot forum for this or similar issues has turned up nothing.

Has anyone experienced this?

 

Thanks,

Chuck

 

Edit:

I added another screenshot of additional glitchiness, plus a video that shows the rotational invisibility.

Thanks for looking,

Chuck
