Short description of error
Weird Z axis rendering in the 3D Viewport when moving close to the center of the scene.

Exact steps for others to reproduce the error

Start from the default scene and delete the cube
Activate Z-axis in Viewport Overlays
Zoom to the center of the scene and rotate up and down
The blue Z-axis overlay vanishes close to the center of the scene and only in the positive direction

This is probably normal behavior, and is related to the viewport camera's clipping settings.
Lower your 'Clip Start' setting in the View side panel (N panel) and it will probably fix it.

This sounds like a clipping problem, as mentioned. This is not a bug.

For information, camera clipping is not the same as view clipping. Anyhow, view clipping at 0 does not change anything.
This ticket might be rejected but please make sure it is intentional before closing a second time ;)

I attach screenshots to make it clearer.

View from top (Z-axis vanishes near the scene center):

View from bottom (Z-axis is always plain):

I think that what gives you your 3D view is usually referred to as the viewport camera.
But yeah, it seems as if you can get the Z-axis to glitch at various viewing angles and projection modes.

@antfarmar Thanks for clarifying the term, it is better to clear up ambiguities.
And thanks as well for checking by yourself and spotting new glitches.
Of course, it is not a big deal, just a little display bug on Z-axis. No idea why it does not happen on X and Y axes.
