I’m experiencing a similar issue when using WIP build (7.0.20252.11325, 9/8/2020). All the blocks wholly visible in the viewport disappear when I execute a move/rotate/gumball move/gumball rotation. This behavior is limited to the perspective viewport, and I’m experiencing it in wireframe, perspective, rendered, X-ray, and ghosted display modes, but NOT in technical, raytraced, or derivative views.
This issue occurs sporadically, and I can’t get 100% reproducability. It seems to be a function of zoom distance/camera distance to target. The below file seems to exhibit the behavior when the following steps are executed:
- Select a block
- Hit esc
- Blocks disappear until they are re-selected (they are still selectable)
The attached example file exhibits this problem for me at the saved view. Hopefully the results can be reproduced if a block (one of the L shaped polylines) is selected, the user hits esc, and then zooms out immediately.

Fortuntaely working in one of the other view modes is an ok-work around for the time being.
