Have to update, after a boolean subtraction while using X-Ray the issue was there too.

Hi Marco -
Could you try a few things and see if any of that makes a difference?
I see you’re on macOS 12.5.1 - could you update to 12.6?
Does it make a difference if you only use one monitor?
Is this issue model-specific, or does it also happen with, e.g., a simple sphere in a new document from a factory-default template?

So did two test:
On the same MacMini M1 as first post report (MacOS 12.5.1) detaching second Monitor (HDMI) and using the one on the USB-C/Thunderbolt connector the issue remains as soon as I switch to Ghosted. (I suppose it should happen on X-Ray too at this point.)

Second test:
MacBook Pro M1 Pro (14") with no external monitor *(MacOS 12.6) no issue at all when using Ghosted nor X-Ray. !!!

(btw, Technical, artisitc, pen are not working all . Are they still not available on this WIP build?)

I’m going to update Macmini to 12.6 too and than report to you.
Here it is:

Updated the MacMini to 12.6.
Issue is still there when switching to ghosted as per attached videograb.

Further test on the MacMini.
Detached the first Monitor (Huawei Mateview USB-C) and used only the second one (AOC HDMI) :
New file model: just a cube, made a boolean subtraction with another cube and no issue on the various display mode available.

WIP model of an historical building: no issue on the various display mode available.

At this point I wanted to try and use the Mateview with HDMI connection too instead of the USB-C and it has worked for a while before starting to go dizzy

I noticed that in all the display modes (except for wireframe and rendered mode, which stay ok) as soon as I zoom in the model and the view became more complex (much more stuff to render I suppose) it start to slow down and scatter on zooming/panning/rotation and then the display issue appear.
The issue seems to be more consistent across using USB-C than HDMI but I’ve met it even using HDMI,

UPDATE for MacBookPro 14 tests:
after a while, in a similar zooming situation like on Mini (close up of the model) using Ghosted mode the display went dizzy.
It worked but just longer if compared to MacMini.
