Do you know the magic setting to switch that feature off?
I’ve never seen this behavior- try 3.6 LTS?
Thats strange and why is there the wireframe visible on the spike at the left even when its solid?
Check/Update your gpu drivers, but could also be intentional for an addon you have there.
Wait are you still working at such a small scale as in your other question?
Try to scale up to about the size of the default cube and try again. If you are really still working on such a small scale here, then be aware. you are really stressing blender numerically here. If you need to work at such a small scale you should work at a magnitude higher/larger in blender and change dimensions via the export itself.
All sorts of graphical glitches can happen otherwise as you much faster reach the floating point limits.
The depth buffer min value as mentioned in the next post isnt really the problem itself. Its rather the range the depth buffer has to cover. So reduce reduce the “clip end” by the same multiplier and the depth buffer is as precise as before. A unit scale change is an option, but doesnt cover every aspect of blender aswell, like physic calculations, just be aware of that.
@sphericall : That happens when your Clip Start is ridiculously low - check your other thread for an answer to this.
See here…
Also in above vid is how to properly work in the sub-millimeter scales… you need a unit scale matching your Length setting and you need to match that in your grid scale setting and things should work as usual.
e.g. Micrometer scale models:
Good luck.
