Model disappears in some views

Hi,

I have the same issue on Mac Rhino 7 (7.6.21127.19002, 2021-05-07), where sometimes, I realise some, not always all, objects have disappeared in top view, while they still appear in perspective view. I tried resetting “4View”. The only way I found to have them showing up on screen was the clumsy trick of duplicating the layer and deleting it. But you have to rename it, re-assign it a colour…

Any ideas? It’s funny to see a similar issue 4 years later.
Regards,
Georges
