Constrain axis always draws on top [covers mesh in unfavorable ways]
Confirmed, NormalPublicKNOWN ISSUE

Description

The mesh outline is not visible when extruding or moving along the axes. The axes overlap the faces of the mesh themselves, and because of this, it is not convenient to precisely position the extruded faces.
It exists on all versions of the 2.8x blender.


To repeat the problem, you can select an edge in the editing mode and simply drag along the y axis. In this case, the contour will not be visible by how much it is moved from its actual position.


With the same action in 2.79, I see black the contours of the mesh as far as it changes when moving.
Bring it back as it was in 2.79

Event Timeline

I think this is the constrain axis always drawing on top of everything else.
2.79 seemed to draw this with depth checking, but that couls also lead to ugly z-fighting [which on the other hand does not happen in 2.8]:


or be covered by geometry completely (still thinking if this is good or bad)

Agree though that four your particular usecase, this is a disadvantage/regression.

@Clément Foucault (fclem), @Jeroen Bakker (jbakker): was this a concious decission? Maybe a compromise could be to draw geometry on top in ortho?

In any case, this is probably not a bug, but a (justified) request for improved behavior, will let above two decide on this.

This is most likely not a mistake agrees.
This is not very convenient only in orthographic mode.

In vertex mode, at least points are visible and you can navigate along them.

Can I set the transparency of these axes in color?


It can be either an option or the ability to disable some things like backlighting, etc.?

In this window for example?

Clément Foucault (fclem) moved this task from Backlog to Known Issues on the EEVEE & Viewport board.

This is a known limitation. The edit mesh wires do not write to the depth buffer because of anti-aliasing. But the rendered meshes correctly cover the constraint axis lines.

I hope to fix this at least 2.90?
